The 6 Best 6.5 Oil Filter adapters (2023 reviews)

The allstar 6.5 oil filter adapter's material feels more premium than its price would suggest. This adapter is designed for replacing a canister style oil filter with a spin on filter on 68 and earlier chevy v8s. It is great for deleting those leaking oil cooler lines on most 80s-90s gm products. The oil pump forces the oil through the filter then into the engine.

This part bolts to the block, and the filter screws onto it. It is universal thru the vortec years. It will fit as long as you have a spin on filter. It is great replacement for damage or missing oem oil filter adapter. This adapter just eliminates the oil cooler lines.

Why We Like This:

Inexpensive fix for perpetual oil leak
Inch long button socket head plain finish
Great for deleting those leaking oil cooler lines on most
Well made, installs easily, no bolts included
