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 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.

Great product!

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

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.

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

Makes filter change on a Porsche 944 Turbo super easy.

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.

Easy to remove, high quality and reasonably priced.

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.

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.
