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.

Enginetech Rebuilders Valves
For about the same cost of reclaiming valves, you can install brand new Enginetech Rebuilders valves. The purpose of these patented Enginetech Rebuilders valves is to help simplify engine rebuilding by salvaging worn cylinder heads and reducing the need for expensive parts like valve seats and springs. Designed with oversized heads and stems, and a lowered keeper groove, these specialized valves create a more efficient and cost-effective rebuild process. The Enginetech one-piece intake valves are made from HNV-3 high alloy valve steel (often used for exhaust valves). All of the valve stems are either triple chrome plated or gas nitrided. Enginetech even goes a step further and hardens every valve tip to 50HRC minimum. The Enginetech exhaust valves are also a one-piece design. All Rebuilder's exhaust valves are made from EV-8 or EV-12 stainless steel. Again, like their intake valves, all stems are triple chrome plated or gas nitrided. Wafer tips, hardened to 50RHc, are inertia welded to every tip. Select the valves you need for your engine rebuild.
