K@N air filters

[Carrera2]

Has any of you guys fitted a performance air filter. Not to sure if there are any gain's in fitting one. Apart from looking neater than the large air box.

[Ian Comerford]

There is often debate about the value of these.  The gains appear very marginal and are outweighed by the potential damage caused by letting more air and therefore more dirt through.  Wisdom appears to be to stick with the standard Porsche item

Paper filters work better seems to be the majority response.

I like neat and unclustered, but you need more than just filters 🙂

Thanks that was very interesting and looks like you got some great results.

I got the filter fitted today and the car is running and ticking over nicely no surging in revs so pleased with that. Not really much of of a difference in sound on reving. Not had a chance to run the car yet on the road but hopefully get her out soon. The engine bay certainly looks more spacious and looks better I think.

Where did you get the filter adapter from? I have bought several in the past and none have fitted.

I changed mine to a K&N dry filter and it does sound better. The biggest improvement was to the engine bay. Changing the filter and performing a heater delete really cleans up the engine bay and exposes those lovely intakes!

That is a nice engine bay. I was wondering what the black box was 😀 but never investigated. Love the red parts .

Thanks! Got the red bits powder coated by a friend who owns a company in Borough Green (Kent). The engine was rebuilt in 2018 and I did it while the bits were off. The trickiest thing was to remove the heater stuff but still route heat to the passenger cabin, had to do a tiny amount of rewiring and ended up with the clean look and not freezing when it's cold.

Can you tell me where you got the air filter adapter/flange from? I have bought several in the past but none have fitted.

Thanks

Hi Brads,

I also could not find one that fit exactly so I bought one that fit the bolt holes and then machined the inside using a dremel until it matched the shape of the intake on the MAF. I was also careful to make sure there were no rough edges. Hope that helps.

Hi Beaky, can you tell us more about the replacement you've used for the MAF? Is the signal compatible with your original ECU  or did you go full Motronic (£££'s)? Thanks.

[Carrera2]

It's in the thread earlier on suslysurdi. Great bit of reading 😊

Thanks Beaky, strolled straight past the link and missed it! Good read by the way, wish I'd gone 3.4 in my rebuild now, next time.
