hi jura, thanks for the info, i just feel on boost just now this k&n is holding the car back, and need to be bigger whats the rough sizes of rcm one?

grant

 

Hi grant

Sizes/diameters RCM are 170mm high with a 160mm diameter mounting flange(you will need some sort alloy trumpet,if you buy only filter without the alloy trumpet),similar is GGR like price-wise and quality

I never run in wing any filter and due this can't compare running with the inner wing filter and in engine bay filter

You are running some sort the Cold air induction feed for your inner wing?

yeah this is the first time i have run one of these myself, japspeed kit hard pipe comes straight off intake through existing wing hole and down to near fog cover still a bit behind it and dont get any bother from water or anything like that temps cooler than engine bay, and especially when 20g is fitted as the heat they produce is massive, could run in engine bay again but i think the heat would be a problem,

 

I'm running a Ks tech mega maf short ram induction kit with cold air feed from fog cover and it works a treat!!!

 

got sorted direct from the k&n website they basically do any size you want so ot a 10 inch filter that should do the trick

 

Im using RCM on a 20g and im very happy with it too.
