Cheddar Bob Posted August 8, 2020 Report Share Posted August 8, 2020 Has anyone noticed if this has changed your engine sound on induction at all,? Link to comment Share on other sites More sharing options...
antjrice Posted August 9, 2020 Report Share Posted August 9, 2020 I used to buy these for other cars in my 'yoof' but to be honest, I couldn't detect a difference although felt the comfort that it was a well engineered filter. I put one in the 986 I owned when I originally bought it but went back to OEM and stayed there for that an my next Porsche as someone on here pointed out that Porsche's R&D and manufacturing is probably equal to or better than K&N....

Have you seen the k&n panel filter demonstration at car shows? I've always thought it would be easy for manufacturers to make this sort of change but they never seem to. Wonder why Link to comment Share on other sites More sharing options...
Boxsum Posted August 9, 2020 Report Share Posted August 9, 2020 I’ve recently changed over to a K&N panel filter, easier than changing the whole filter box from the 987. Can’t report on changes yet haven’t run it long enough but definitely changed the induction noise so guess it’s doing something Link to comment Share on other sites More sharing options...
Berni29 Posted August 9, 2020 Report Share Posted August 9, 2020 Hi I always keep away from these things for cars using a MAF sensor because of potential contamination issues caused by the filter oil. I am pretty sure they do not flow any more air than than a clean standard filter when fitted in the enclosure. Berni Link to comment Share on other sites More sharing options...
Ninesomething Posted August 9, 2020 Report Share Posted August 9, 2020 I agree. Although I have had them on a couple of cars and never had MAF probs. I were going to upgrade my filter ( and I prob will at service time) I'd get a Sprint. No oil on those and most people report more growliness. B&M also get good reviews but I can't offhand remember if they have to be oiled or not. Link to comment Share on other sites More sharing options...
Cheddar Bob Posted August 9, 2020 Author Report Share Posted August 9, 2020 I've pretty much always used a K&N filter on my performance cars, but its been an induction kit. The sound was the attraction, not the performance claims, although it made a huge difference on one of my swift gti's as the air box was very restrictive for the engine tune. Motorbikes, always swapped for a k&N for easy of maintenance. Wanted to improve sound, so got my answer above thank you Link to comment Share on other sites More sharing options...

mortzz Posted August 10, 2020 Report Share Posted August 10, 2020 i have K/N panel filter in and can say it should be far superior to the OEM filter , just ensure it gets cleaned correctly Andy Link to comment Share on other sites More sharing options...
Jord Posted August 11, 2020 Report Share Posted August 11, 2020 my take on this would be the K&N should allow more air to pass through it but its my understanding you have to maintain them more than the usual throw away OEM version. Link to comment Share on other sites More sharing options...

If by maintain you mean clean it rather than throw it away then yes. Paper OE filters are disposable. Link to comment Share on other sites More sharing options...
Cheddar Bob Posted January 9, 2021 Author Report Share Posted January 9, 2021 I've seen a couple of videos which report the filters won't sit well in the filter housing. Did anyone have any issue with this? Lee @ cps said they were a pig to fit, and he prefers not to but is willing to have a go at my request at my next service.

Paper OE filters are disposable. Yes, with the cleaning fluid and then re-oil it which then can lead to oil contamination on the MAF if you are too generous.

edc Posted January 9, 2021 Report Share Posted January 9, 2021 You can over fill the engine oil too. Like most things in life too much isn't always a good thing 😂 I've used the K&N on both my Bkxsterd and never had a problem. I've used them and Green filters too on various other cars and also never had a problem. Link to comment Share on other sites More sharing options...

edc Posted January 9, 2021 Report Share Posted January 9, 2021 Fitted fine in both 986 and 987 airboxes. Link to comment Share on other sites More sharing options...
Natplant Posted January 9, 2021 Report Share Posted January 9, 2021 I fitted a BMC replacement panel filter, fitted perfectly and made a noticeable induction sound difference. Link to comment Share on other sites More sharing options...
Cheddar Bob Posted January 14, 2021 Author Report Share Posted January 14, 2021 Ok so after a little confusion with the year of my car, turns out this will fit fine so Lee has ordered one and will fit it at the service next week. Link to comment Share on other sites More sharing options...
edc Posted January 14, 2021 Report Share Posted January 14, 2021 Doesn't matter whether you have a 986 or 987 as I've put K&N into both airboxes and both fit fine. Across the 986 range it's the same airbox and same across 987 range. Link to comment Share on other sites More sharing options...

Definitely, but not sure that that was a good thing. A bit like the equal-length tubular manifolds altered the Boxster Burble and again I don't think it was an improvement. Now the Oettles Mod is another thing entirely, that should be standard IMHO Link to comment Share on other sites More sharing options...

It's got the 987 airbox. I should have written all the regular inferior 986 🤣 Link to comment Share on other sites More sharing options...
