Denso Oil Filters

There's a big difference between generic, mass-merchandised oil filters and top-quality filters built to strict original equipment standards. The generic filter has a pretty paint job and attractive packaging, but it may not even meet manufacturer warranty requirements. Denso oil filters with First Time Fit design feature a heavy-duty steel case to resist distortion, dual-layer filtration media for maximum engine protection, a molded, pre-lubricated O-ring to prevent leakage, and a silicone anti-drainback valve to protect the engine against damaging wear on cold start-up. As an added bonus, Denso filters also employ an innovative Torque Stopper case design that prevents over-tightening and simplifies installation, a great feature for do-it-yourselfers. Generic oil filters are no bargain. Denso First Time Fit oil filters protect your precious vehicle investment. Features and benefits of Denso oil filters include: * One of the world's premier OE oil filter suppliers * Each oil filter is put through Denso's rigorous manufacturing and testing process * Efficient paper media protects engines against contaminants * Silicon anti-drainback valve prevents rough starts caused by oil draining out of the engine while turned off * Pre-lubricated molded O-ring seals better than gaskets used by other brands

Clevite H-Series Rod Bearings

Clevite H-Series rod bearings were developed primarily for use in NASCAR type racing but are suitable for all types of competition engines. These H-Series bearings have a medium level of eccentricity, high crush factor, and have hardened steel backs and thin overlays.

H-Series bearings are recommended for use with crankshafts that have oversize fillets and where engines run in the medium to high rpm range. They should also be used if contact patterns obtained with Clevite P-Series bearings are too narrow. Contact patterns should ideally cover 2/3 to 3/4 of the bearing surface.
