It doesn't look or sound as nice but the cold air is channled straight to the box. Without good ducting anda custom heat shield you will be taking in hotter air which will reduce the engines performance. By how much I'm not really sure TBH.

really?? ok thats interesting to know ill probley keep it stock then. thanks adam

 

ive got an apexi system on mine with a heat sheild and a cold feed pipe direct onto the cone filter ,it sounds a lot better than stock and imo is more responsive.and looks good when you open the bonnet .

going to change the plastic pipeing for crome .for the slight difference it makes if any go for a good cone filter [not hks]

 

can take a pic if you want ?

Don't do it. I have got the chrome pipe that replaces all the stock plastic stuff, from filter to inlet.

I put it on mine and it made a huge difference to performance, Not in a good way. I got a big flat spot where the power normally picks up and it ran terrible.

Poor filtration would/could cause dirt to be drawn into the engine for one

 

but that would apply to a stock system as well

 

i put my stock one back on for a few days to see if all "the keep it stock " suggestions would be better i found no difference except there was no induction noise.
