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.

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.
