K&N Premium Oil Filter: Designed to Protect your Engine: Compatible with Select 1983-1995 PORSCHE (968, 911, 944, 924, 944 S), HP-4001

Works great on older Porsches, or any vehicle with a tight space. All you need is a 1 socket to tighten the filter.

This is the only place I get my filters for my Porsche

Great for these engines, not a K&N fanboy and dont plaster their stupid stickers everywhere, but they produce a quality product, and the top nut allows easy removal as usually the clamp on the coolant line below the cam tower blocks you from using a regular oil filter socket. Make sure to use a 6 point 1inch socket instead of a 12 point, the 12 point will strip and skip on the welded on nut very easily.

Great product!

Fast delivery good product

Easy to install and offers good filtration for your oil!

Works great on my 1987 Porsche 924S with the 2.5L N/A engine. Have had no issues using this filter. The nut on top makes removal a breeze. Nut is socket size 1 inch.

Quick filter change. I use one every other oil change and they hold up well. K&N makes quality thats needed on these old blocks.
