HP-1004 (Z79)

Suits, Honda models up to 2000, later models use a HP-1010(Z547) please double check. Durable Construction for Extreme Conditions To satisfy the demands of racers, K&N oil filters use thicker canister walls for extra strength and durability which reduces the risk of damage from loose rocks and debris. The durable construction will withstand higher oil pressures found only in racing environments without bursting. The drilled hole on the nut is for a safety wire attachment. Required for many types of racing, the safety wire prevents blown oil filters from falling on the track and representing a hazard to other race vehicles. This extra engineering offers peace of mind for consumers who want only the best. For application/catalogue see link below.
