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

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.

As advertised.

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.

We purchased a couple of these oil filter for our 1993 Porsche 968, fitment was perfect and the price was the best we could find.

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.

Fast delivery good product

Product as expected, timely delivery

If for some silly reason you just want slightly more oil capacity on your Honda or other M20x1.5 specd car, heres a possible option. It doesnt necessarily cost more, so go ahead and be that guy. Good choice for oil filter relocation kits. Can work for engines that use HP-1004 (and less likely HP-1010). Directly fits Honda F23A. Yes, oil pressure is in spec with this combination. This filter is over 5 tall, so your vehicle needs to have something like 6-7 of space between where the oil filter mounts and the opposite obstacle. I recommend getting it over with and buying a 1 box end ratchet if you dont already have one. Not like you wont use it.

Makes filter change on a Porsche 944 Turbo super easy.
