Any negative affects from oiled air filter installation?

This debate has been done to death on some of the biggest car forums in the world . Buy any Ferrari or porsche . Open the engine air filter box and see what inside. Chances are its a dry paper filter.

I chose my side of the debate a very long time ago. I am just purely interested in if they damage MAF'S on 940's. I generally run cars so old its irrelevant. I am purely interested in maximum airflow through the standard airbox without detriment to the engine or ancillaries.

Technically these uprated style filters do filter less than paper which is why they can flow a little more. I care not for what the sale speel has to say about it as they filter well enough for me regardless haha

The standard 940 turbo Air box is cold air feed as standard so a standard filter is the best way to go, I replace mine on every service even if it has only done 3k miles as you can get them for about £4 from Euro Car Parts. There is no warm air feed etc in a turbo 940 air filter housing, I've gutted the excess plastic and foam padding from inside mine to give a more pronounced wastegate noise when I let off the throttle but that's about all you need for a mildly tuned 940.

Save your money and go through and service it properly as it will no doubt be leaking oil, the PCV probably won't have been cleaned out properly for a long time and if you want a decent mod then get rid of the useless camshaft it has as standard and go for an A, V, VX3, H or K cam or if you want to go more serious then an IPD turbo cam, I have the IPD cam in mine and it seriously wakes up the engine.

Hopefully that advice is of use

Thanks it is buddy it all is , No cam changes yet though haha. I think i will do the same as you and clean airbox out and also look at adding additional air intake to the airbox. From my own personal experience its the more cool air the better within reason

I run an oiled cone K&N in the 360 with B230FT, its extremely loud on the dump and you get alot of turbo noises. The younger lads love it, but I was going for the sleeper scene.
Other than that it runs fine, I havn't oiled it since I got it, seems dry enough and doesn't do alot of miles.

LOL, i had a cheap cone filter on recently as a temporary measure, it made my turbo sound better than my mates Skyline!!!

The standard air intake on my 940 was from the front of the engine bay, I cut out a section - which was pretty obvious and there was a purpose made connection to the outside from the side of the box - take your air box out and have a look.

I also removed the foam as it can disintegrate over time, all it does is dampen noise so best remove it before it causes a problem. You do get a bit more wastegate noise but its not too noticeable and certainly not boy racer at all.

I also had a good research and unless your are running monster power theres little point in changing the standard air box.
