K&N Nissan QR25 Performance Gold Oil Filter
Regular Price: $17.70
Special Price $15.98
Fits all QR25 Engines (all years/models) Each K&N Performance Gold Oil Filter comes with a 1” nut welded to the top of the canister so they can be easily wrenched-off with a standard tool. K&N Performance Gold Oil Filters use resin impregnated cellulose filter media. This allows for higher flow rates while providing outstanding filtration. High filter flow rates are important in racing vehicles where heavier grade oil is used and the oil is pumped much faster than in a standard vehicle. When the engine is circulating oil at high GPM rates, the high-flow oil filter helps reduce the loss of pressure through the filtering process. FEATURES * Drilled safety wire holes for racing in canister oil filters * Sturdy 1" (automotive) or 17 mm (motorcycle) wrench nut, where applicable, makes oil filter removal quick and easy * Heavy-duty construction * Resin-impregnated filter media provides maximum filtering surface for contaminant removal * Anti-drainback valve (where applicable) eliminates dry starts, prevents oil from draining back into crankcase during engine shutdown * Internally lubricated gasket provides positive seal while allowing easy on and off of filter * Rolled threads provide extra protection against stripping Learn More -

Cometic Tri Layer Metal Headgasket - B15 or B16
Regular Price: $159.99
Special Price $139.99
Now available! For the B15 or B16. .030" standard thickness, 89mm bore size. Custom sizes available but take several weeks to produce. Using 1mm oversize pistons, choose 90mm bore size. Provide maximum sealing performance for today’s high output engines and require no sealants. MLS gaskets are ideal for both aluminum heads to aluminum blocks and aluminum heads to cast iron blocks. They can withstand the shearing force created by the two materials. MLS gaskets have increased strength because they are comprised of multiple layers of stainless steel; which also creates the ability to rebound and resist corrosion. The outer layers are embossed and coated on both sides with Viton (a flouroelastomer rubber based material that is heat resistant to 250 C/ 482 F). Viton is designed to meet the demands of a variety of harsh sealing environments, load conditions, and surface finishes. The center or shim layer is uncoated stainless steel, which can be varied to accommodate multiple thickness requirements. Learn More -
