Hey Guys I am having a 3" milltek exhaust system fitted to my 2006 spec-c and what I am wondering is should I have a induction kit fitted or a drop in filter.

Be advise on what would be the best makes to go for, for either option please.

The general thoughts about induction kits don't seem to be very positive around these parts.

Most,not all,people will say just replace the panel filter for something like a Green Cotton one.

Panel filter is always teh best way to go... Induction kits draw in hot air and every +1 degree increase in inlet temp is power lost!

Some foolish people even believe putting a piece of "cold air" ducting cures this problem..Hmmm let me think several thousand gallons of air up a small 'open' pipe... Yeah okkkkkkkkkkkkkkkkkk

don't forget the size of the hole that is in the schnorkel isn't that big either

Are you reffering to the intake on the airbox, if so its a different kettle of fish as its sealed to the air box so there is no alternative route for the air If your induction kit is sucking away it will be drawing in the less dense air from around it in the bay not the cooler air outside up the silly little pipe

The schnorkel is in the wing but i agree (especially as the OP has virtually a new car) that unless properly sheilded the ik is not good

So drop in filter is the way to go.
Thanks guys.

But then fitting a CAIK (Cold Air Induction Kit) is a completely different matter. Not hot air then.

That's right... If you're even thinking of fitting a cone filter, it must be totally shrouded so that it's insulated from the underbonnet temps., and that only cold air via an intake positioned, preferably, so that it draws mildly rammed air in from the front of the car, is used. Because any potential gains you may achieve with a higher flowing cone filter in the first place, will be immediately negated (and then some!) if the above steps aren't taken.

If you're not willing to have the shrouding, ducting, etc., then best save your money and get decent panel filter like the Green...

Panel Filter all day long unless over 350 BHP (ish)

Green cotton pannel filter is the way to go im guessing?

Or an APS CAI kit, These are ment to be very good

If you are only planning to go up to 350bhp i would stick with the panel filter because your twin scroll turbo will be out of puff anyway
