K&N Performance Gold Oil Filters

Get oil filtration that's as good as gold with K&N Performance Gold oil filters. Keep your engine free from contaminants as small as 10 microns. They use a resin-impregnated filter media to provide maximum filtering and an inner core to lend extra structural support to the filter, preventing filter collapse. Plus, many of these K&N oil filters have an anti-drainback valve (where applicable) that eliminates dry starts and prevents oil from draining back into the crankcase during engine shutdown. And they're protected by a heavy-duty outer shell that guards against rock and stone damage and provides over 550 psi hydrostatic burst strength. So, if you want golden-level oil protection, then you want K&N oil filters.

Cam Motion Titan LLR Series LS Camshafts

Cam Motion LLR Series LS camshafts are low lash solid roller-style cams designed for performance enthusiasts who want maximum performance from their LS and Gen 5 LT-powered vehicle. These camshafts deliver the precision high-rpm valvetrain stability that solid cams are known for, with the low maintenance dependability and quiet operation that makes sense in a modern vehicle. Designed for max street, street/strip, and race cars, Titan Kings will have a heavy lope at idle and explosive power in a vehicle equipped with the proper high stall torque converter, rear axle ration, and supporting intake exhaust that's been modified or designed for high flow. The cams enable drivers to get the most from their stock bottom end engines. They're engineered to fit without the need to fly-cut valve reliefs in the pistons; however, it's the owner/builder's responsibility to assure safe clearance. Titan Series units feature Cam Motion's renowned smooth cam lobe design, providing quiet valvetrain operation and excellent upper rpm stability. They're offered in top-of-the-line 8620 camshaft cores.
