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. They also have enlarged chamfers for greater crankshaft fillet clearance and are made without flash plating for better seating. Bearings with .001 in. extra clearance are available for standard size shafts and with or without dowel holes. 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.

NGK V-Power Spark Plugs
NGK V-Power spark plugs offer economical performance for nearly any automotive application—and they're the only plugs with NGK's V-Groove technology. These plugs enhance ignitability, lower the voltage requirements of ignition systems, and have strong anti-fouling characteristics, while improving fuel mileage and acceleration performance. The V-Power plugs are also highly durable against electrical and chemical wear, making them long-life replacement plugs. Because of the V-Groove, the spark occurs at the edge of the center electrode—so heat is not absorbed by the electrode itself. This allows the flame kernel to expand quickly and efficiently for a complete burn and great performance. More than a hundred models are available, both universal and application-specific; order the plugs designed for fitment on your vehicle.

WIX Filters Oil Filters
WIX oil filters play a vital role in in your vehicle's lubrication system, protecting your engine from premature wear. As gearheads know, every moving part in the engine requires clean oil! WIX oil filters trap more dirt than the leading national brand, and they keep filtering long after the competition has completely quit. WIX patented the first spin-on oil filter in 1954 and has been at the forefront of filter technology ever since. Canister-style oil filters feature strong, full-metal base plates to prevent leaks at the double seam under severe driving conditions. They also offer glass-enhanced media that improve each filter's ability to catch and hold engine-damaging dirt. Choose the WIX oil filter to fit your make and model—for a cleaner-running engine over many extra miles.
