This may seem a silly question but before people should me down and say "The APS one obviously" i do remember reading that some people found the filter they supplied to be slightly on the restrictive side.

I have recently come in to possession of this CAI and as far as i am aware it has a K&N filter with it (as its not new)

So therefore i was wondering if there were any recommendations out there as to what i could replace it with for best performance.

Green seem to do a massive range of replacement filters but im unsure as to the bore of the APS pipe so have held off thus far.

Does anyone have any other suggestions?

 

john banks did some tests with the original filter and said it made no difference changing to a bigger filter even at 420 bhp ish, i had the original filter on mine and had no problems

 

Hi Neil,

I have one of these on my car. I have replaced the K&N Filter with a quickshift racing one this has a very fine steel mesh like the Blitz SUS filters. I had to get an adapter plate from quick shift and a bit of silicone pipe to mate the pair up. I cant remember the dimensions but I have been running circa 400 bhp without any problems for around 12,000 miles. Although the car was mapped to the steel mesh filter and not the K&N. I did have some MAF issues with the K&N as its one of those filters that has a fine oil on it.

Hope that helps

Darren

 

ok well as the kit im getting comes with a K&N ill have to assess it from there then.

Id probably only get a new'un if the one it comes with looks past its best anyway.

 

Thanks darren thats useful too. I quite like the idea of the mesh filter but only if i left the foglight out so it would protect the filter a bit!

 

Mine has the P1 Driving lamps instead of the OEM fog lights but I have removed the orange wedges to aid the flow to the filter.
