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

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.

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

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.

As advertised.

Fast delivery good product

Easy to install and offers good filtration for your oil!

Great product, fast delivery.

Easy to remove, high quality and reasonably priced.

What can be said; if you want the best by K&N. The price was WAY cheaper than any discount auto parts store.

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.
