SCE Vulcan Cut-Ring Head Gaskets
SCE Vulcan cut-ring head gaskets are hybrids forged to harness the best sealing properties of two head gasket types—composite and stainless steel. With no sealant needed, the pliable, perforated metal-core composite bodies eliminate coolant and oil leaks, while the solid stainless steel cut-rings "bite" into the cylinder head forming a positive barrier against combustion pressure leaks—without machining. SCE Vulcan cut-ring head gaskets are designed for use with high-static compression or forced-induction engines, which are prone to combustion pressure leaks when using typical composite or MLS head gaskets.

EBC Bluestuff NDX Brake Pads
EBC Bluestuff NDX brake pads are made with a high-friction sport and race material that can be used for aggressive street and certain track applications. These replacement pads feature great bite when cold, a progressive brake feel, and the ability to bring a car to a complete stop. Deep V-grooves assist in venting—and catching the dirt, dust, and debris that are inevitable in track use. The EBC chemical interlayer system used on Bluestuff NDX range pads is a harder material designed for heavy-duty race applications requiring the extra security of bond strength. The effect of the interlayer is to triple the shear strength of common organic brake pads over non-interlayer versions. These pads bed-in quickly and easily, wear evenly, and are less harsh on rotors than other race pads. For true race-quality braking that can go from the track to the street, order the EBC Bluestuff brake pads designed for fitment on your make and model.

Funk Motorsports Turbo Heat Shields
Funk Motorsports offers turbo heat shields for a wide range of (universal) applications, as well as vehicle-specific models for select BMW, Honda, Ford, and Subaru vehicles from 2002 and up. These turbo and/or turbo wastegate thermal blankets work to insulate the hot side and retain the heat within the exhaust gasses themselves. Hotter gasses accelerate faster, leading to them leaving the system sooner—improving spool up and throttle response. Insulating the turbo also helps to lower the amount of heat that dissipates into the engine bay and intake pipework. A cooler intake results in higher performance and more consistent power figures over time. The 4-layer shields are offered in three finishes: titanium twill, carbon fiber twill, and inside out (for turbos in contact with a heat source). Additional details: * Inside-out blankets have internal material mirrored on the outside, as well * Available for a variety of turbocharger and wastegate styles * A turbo is an absolute furnace within the engine bay. Excess heat produced by the turbo can cause devastation to surrounding sensitive components. Protect anything from oil lines, coolant lines, electronics, and even bodywork positioned close to the turbo from the dangers of excess heat * Funk shields feature specifically developed thread construction to allow for exceptional durability when removal is necessary for routine turbo maintenance. The new fireproof ultra-high temperature stainless steel thread is around 1mm in diameter and can now remain highly durable with temperatures in excess of 1,300 degrees C * New, thicker internal heat lagging insulation provides up to 3x improved heat reduction. This insulation wool is created from a ceramic silica complex matting to improve durability over prolonged heat cycles, as well as insulation quantities * ROHS tested and approved to ensure compliance and desired parameters * NOTE: Turbo blankets are not flammable. However, if any flammable fluids are introduced into close proximity of the blanket, the blanket could become a suitable ignition source for a flame to be produced. Please ensure that all necessary precautions are taken in regard to the appropriate maintenance of all oil and fuel lines and fittings surrounding the turbo charger and fuel injection system. Funk Motorsports takes no responsibility for fluid contamination their products.
