ACPERFORMANCE Products

The AC PERFORMANCE Braided Stainless Steel Brake Hose Kit is a heavy-duty braking upgrade specifically designed for GM vehicle owners. Whether you are restoring a classic car like an El Camino or simply looking to enhance the stopping power of your daily driver, this kit aims to replace aging factory rubber hoses with high-performance materials. It is an essential modification for automotive enthusiasts who demand reliable, responsive braking under heavy loads.

At the core of this kit is a robust PTFE hose wrapped in braided stainless steel, which is then sealed with a clear PVC coating. This multi-layer construction not only prevents the line expansion commonly associated with standard rubber hoses but also offers exceptional resistance to corrosion, rust, and abrasion. The hoses are 100 percent pressure tested at 4000 PSI and boast a staggering burst pressure of over 12500 PSI, ensuring they can handle extreme braking scenarios without failure. Furthermore, the impressive temperature tolerance of -70 to 260 degrees Celsius guarantees consistent performance in virtually any environment.

In terms of real-world performance, upgrading to these braided lines significantly improves brake pedal feel, eliminating the spongy sensation and reducing stopping distances during panic stops. The kit is quite comprehensive, providing two 18-inch lines, weld-on tabs, mounts, clips, banjo bolts, and copper washers. This generous inclusion of hardware makes the installation process much smoother for DIY mechanics and professional installers alike.

However, while the overall build quality is stellar, there are some fitment nuances to keep in mind. A few users have noted that the included fittings do not work seamlessly with all GM setups, particularly certain metric calipers. Depending on your specific make and model, you might find yourself needing a quick trip to the local auto parts store to pick up alternative adapters to complete the installation.

Ultimately, the AC PERFORMANCE Brake Hose Kit offers tremendous value and peace of mind for those looking to upgrade their GM vehicle braking system. Backed by DOT and IATF16949 certifications, the superior materials and rigorous testing make this a highly recommended investment for enhanced automotive safety, provided you double-check your specific caliper fitting requirements beforehand.

The AC PERFORMANCE Radiator Coolant Silicone Hose Kit is a four-piece cooling system upgrade built specifically for the 2008-2012 Mitsubishi Lancer Evolution X CZ4A. The package includes four custom-molded silicone hoses and eight SS304 stainless clamps, which covers everything needed to replace the factory rubber lines in one sitting. It is aimed squarely at Evo X owners whose original hoses are approaching or past their service life, and at anyone running elevated boost, a track schedule, or a modified cooling setup where a hose failure carries real consequences.

The specifications tell the story. A working range of -60 to 220 C (-76 to 428 F) and a 6 bar burst pressure tolerance both sit comfortably above what OEM rubber is designed for. That matters most in the situations where stock hoses actually fail: sustained heat soak in traffic after a hard run, repeated thermal cycling over many seasons, and the higher system pressures that come with a stiffer radiator cap. The oil-resistant inner liner is the other practical detail here, since ambient oil mist in a hard-driven engine bay is a common reason factory hoses swell and go soft long before they visibly crack.

Build quality is oriented toward the racing-adjacent end of the market. Multi-ply silicone holds its shape rather than collapsing under vacuum the way tired rubber can, and the custom-molded bends mean the hoses follow the Evo X routing without kinking or needing support. The SS304 clamps are a meaningful upgrade over the plated hose clamps bundled with cheaper kits, since they will not seize or rust in a wet, salted environment. The black finish is a deliberately conservative choice: owners who want a stealth engine bay get the durability benefit without the blue or red silicone look.

There are honest caveats. This is a single-platform part, so it has no crossover value if you sell the car. The listing carries no customer reviews yet, meaning real-world reports on long-term sealing and clamp durability are not yet available, and buyers are relying on the stated specifications. Installation is also more than a bolt-on: you will need to drain the coolant, route each hose, and properly bleed the system afterward to avoid air pockets. As with any silicone hose install, the clamps should be re-checked after the first few heat cycles, since silicone can settle slightly and weep at the joints if left at the initial torque.

The verdict is straightforward. If you own a 2008-2012 Evolution X and are replacing original hoses anyway, this kit is a logical step up rather than a lateral move, because the temperature and pressure headroom, oil-resistant liner, and stainless clamps address the specific ways factory hoses degrade. If your car is stock, low-mileage, and never sees a track, the upgrade is less urgent and standard replacement hoses will do the job. Owners who want a fit-and-forget cooling refresh with margin to spare are the right audience.

Confirm your chassis code first. This kit is molded for the CZ4A Lancer Evolution X built between 2008 and 2012. It is not intended for the Lancer Ralliart, standard Lancer, or earlier Evolution generations, and the custom bends will not adapt to a different engine bay layout.

Plan the job, not just the part. Budget for fresh coolant and distilled water, and set aside time to bleed the system thoroughly after the swap. Trapped air in an Evo X cooling system produces misleading temperature readings and localized hot spots, so a proper bleed is not optional.

Re-check the clamps. Snug the SS304 clamps evenly on install, run the engine to full operating temperature, let it cool, then re-check each clamp. Silicone settles slightly on first heat cycle, and this single step prevents most weeping complaints associated with silicone hose kits.

Consider doing it as a package. If the hoses are old enough to need replacing, the thermostat, radiator cap, and coolant are often in similar condition. Replacing them at the same time saves a second drain and refill and gives the higher pressure rating of these hoses something to work with.

The AC PERFORMANCE Radiator Coolant Silicone Hose Kit is a direct replacement for the factory upper and lower radiator hoses on the CT9A-chassis Mitsubishi Lancer Evolution, covering the 2001-2005 EVO 7 and EVO 8 as well as the 2005-2006 EVO 9 with the 4G63 engine. The kit ships as two hoses plus four stainless G-clamps, which is exactly the scope most owners need when the original rubber has gone soft, swollen, or started weeping at the necks after two decades of heat cycling. It is aimed at EVO owners maintaining a high-mileage car and at tuners running more boost than stock, where cooling system integrity matters more.

The engineering is where this kit separates itself from a stock replacement. The hoses use handcrafted silicone with 4-ply polyester mesh reinforcement and a 5mm wall on the larger diameters, dropping to 3-ply and 4mm on the smaller ones. That translates to a rated temperature range of -60C to 220C (-76F to 428F) and a burst pressure tolerance of 6 Bar, roughly 88 psi. For context, a heat-soaked 4G63 sitting in the pits or crawling in traffic puts sustained thermal load on the coolant system that gradually degrades rubber, and a reinforced silicone hose simply does not balloon or collapse under the same conditions. The oil-resistant inner liner is a meaningful detail too, since engine bay residue and minor seepage will attack an unprotected silicone bore over time.

Build quality reads as purpose-built rather than generic. The molded shapes are specific to the CT9A platform with guaranteed fitment, so there is no trimming, splicing, or coaxing a universal hose into an awkward bend. Silicone also resists UV, water, ozone, and oxygen far better than rubber, which matters for a car that spends time parked outdoors or sees long service intervals. The gloss black finish is a deliberate choice: it upgrades the hardware without announcing itself, unlike the blue and red kits that date an engine bay. The SS304 stainless clamps included in the box resist corrosion in a wet, hot environment and clamp evenly on the silicone, and their inclusion means you are not making a separate parts run.

There are real caveats. No instructions are included and the manufacturer explicitly recommends professional installation, so if you have never drained and bled a coolant system on an EVO, budget for shop time or plan on careful research first. The kit covers only the two main radiator hoses, so heater hoses, bypass lines, and throttle body coolant hoses remain on the original rubber unless you buy them separately. And because this listing has no accumulated customer feedback yet, there is no independent track record on how these particular hoses hold up after several seasons, which is worth weighing if you prefer a brand with a long review history. Silicone also requires proper clamp torque, since overtightening can cut into the outer ply.

Verdict: this is a sensible, well-specified upgrade for anyone keeping a CT9A Evolution on the road or on track. The spec sheet is genuinely stronger than OEM in every dimension that matters for a turbocharged engine, the fitment is model-specific rather than universal, and the stainless clamps round out the package. Factor in installation labor and the fact that this covers the main radiator hoses only, and it is an easy recommendation for the EVO owner doing preventative cooling system work or supporting a higher-boost build.

Note: No installation instructions are included; professional installation is recommended.

Confirm your chassis first. This kit is molded for the CT9A platform, meaning EVO 7, 8, and 9 with the 4G63. It is not intended for the EVO X (CZ4A) or earlier CE9A cars, so verify your model year and engine code before ordering.

Plan the coolant service around it. Replacing radiator hoses means draining the system, so it is efficient to pair this job with a coolant flush, a new thermostat, or a radiator cap replacement. If your hoses are original, the surrounding rubber is likely the same age and worth inspecting at the same time.

Budget for installation if you are not doing it yourself. No instructions ship with the kit and the manufacturer recommends a professional fit. A shop familiar with the platform will handle the bleed procedure properly, which matters because trapped air in a 4G63 cooling system can cause misleading temperature readings.

Mind the clamp torque. Stainless G-clamps seal well on silicone but should be snugged evenly rather than cranked down. Overtightening can bite into the outer reinforcement ply and create a future failure point.

Consider the rest of the system. Since this covers the two main radiator hoses only, owners building toward higher power may want to plan a phased replacement of heater, bypass, and throttle body coolant hoses to bring the whole system up to the same standard.
