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

Makes filter change on a Porsche 944 Turbo super easy.

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.

I have used this American built brand for years across numerous on and off-road vehicles. The specifications of the filtration material and construction are superb. The intergraded top nut allows easier removal and installation than traditional filters.

Easy to remove, high quality and reasonably priced.

As advertised.

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

Fast delivery good product

Product as expected, timely delivery

I know it’s not listed for fitment on Nissan Armadas and Infiniti QX80’s but it’s perfect as an oversized alternative.

Great product, fast delivery.
