Originally developed for demanding race applications, K&N's premium Performance Gold Oil Filter is rapidly becoming a favorite among consumers for its durability and easy removal. Each of K&N automotive and marine oil filters comes with a 1" nut welded to the top of the canister so they can be easily wrenched-off with a standard tool. To satisfy the demands of racers, the oil filter has many features over and above the requirements of most vehicles. K&N uses thicker canister walls for extra strength and durability which reduces the risk of damage from loose rocks and debris. The drilled hole on the nut provides for safety wire attachment. The oil filters also have a resin impregnated cellulose filter media. This allows for higher flow rates while providing outstanding filtration. _x000B_ _x000B_ _x000B_Product Specifications: _x000B_ _x000B_-Product Style: Oil Filters _x000B_-Height: 5.14 in (131 mm) _x000B_-Outside Diameter: 3 in (76 mm) _x000B_-Thread Inside Diameter: 0.75000 _x000B_-Thread Number: 16.00000 _x000B_-PSI Relief Valve: 27-35 _x000B_-Anti Drain Back Valve: Yes _x000B_-Style: Canister _x000B_-Weight: 0.8 lb (0.3 kg) _x000B_ _x000B_ _x000B_Important Link(s): _x000B_ _x000B_K&N Vehicle Applications and Cross-Reference _x000B_ _x000B_ _x000B_ _x000B_Additional Information: _x000B_ _x000B_K&N Premium Wrench-Off?
