Performance Oil Filter GM LS3/LS7/LS9

The FRAM Performance Oil Filter HP18 is a premium spin-on oil filter engineered for high-performance GM LS-series engines, including the LS3, LS7, and LS9 platforms. This is the go-to filter for operators and enthusiasts running serious LS powerplants in tactical support vehicles, pursuit units, and performance off-road platforms where engine protection under extreme duty cycles is non-negotiable.

Built to OEM specifications, the HP18 features a steel construction with orange paint for quick identification during maintenance cycles. The filter delivers maximum flow with optimized pressure drop, critical for maintaining oil delivery to the high-revving LS powerplant under sustained acceleration and high-load scenarios. The 22mm x 1.50 thread fits all supported LS variants, ensuring direct bolt-on compatibility without adapter fittings. At 3.4 inches tall and compact in footprint, the HP18 mounts cleanly in engine bay applications where space is limited but performance demand is absolute.

This filter is standard-issue replacement equipment for fleet maintenance operations, law enforcement motor pools, and serious LS builders who demand consistent filtration without compromise. Whether running a 6.2-liter LS3 in a police interceptor, the 7.0-liter LS7 in pursuit-duty vehicles, or the supercharged LS9 in specialized transport applications, the FRAM HP18 delivers the filtration capacity and durability required for extended service intervals under demanding duty. FRAM's proven track record with OEM suppliers and fleet operators makes this filter the reliable choice for LS-powered platforms operating at the edge of their performance envelope.
