Cold Air Intake For Prolex Induction Kit

[StuP]

Hi, I'm relatively new to LOC so apologies to all the senior members if I'm covering old ground. I've just fitted a Prolex induction kit and noticed that there's not much chance for cold air to flow around the filter as the carbon fibre cold air box wont fit on this type with the pipe running accross the front of the engine and in its standard state the engine bay is pretty well sealed.

I noticed that there is an intake in the bumper immidiately under where the filter element sits but sends air into a void. The only thing seperating this cold air source and the filter is wafer thin sheet metal so i set to it with a 76mm hole saw and hey presto there is now cold air pouring over the filter and a noticable increase in performance. I tidied it all up with a plastic insert and grille to stop leaves etc getting in and it seems well worth it for little or no cost at all. (pics to follow if i can remember how to use photobucket!

I remember another member did this and used a flexi pipe from next to the bottom fog light up through the inside of the wing, to the Prolex Induction Filter.

Yes we need pics to see what you did please :)

Ok here goes... 1st pic shows standard air intake next to OS fog light in bumper.

Next picture is zoomed out showing air feed cut into the thin metal between engine bay and void where cold air goes through the intake (chrome grille over it below red filter)

Last pic is zoomed in on filter element and intake cut into the thin metal.

The original plan was to pipe the air through this cut intake from the bumper intake but i was so pleased with the initial result (not enough time to remove the light and get down into the void to route the pipe) that i think i'll leave well alone.

Hope this makes sense and the pics work!

Looks good mate, but seriously ditch that crap filter before something nasty gets in the engine, get yourself an Apexi one off eBay.

Surely plenty of air gets into the engine bay already, otherwise the OEM air scoop wouldn't work ? Or am I missing something ?

[john99t-reg]

excellent effort, thanks for the idea, i need to do this for my powertec induction kit. if it wouldn't be too much trouble could the size of the first two pictures be increased, thanks

good idea there mate. as sav said get rid of the crap filter.

Thanks Stu, much better......but now I see what looks like you have cut down the old air intake box and reattached part of it, adding a small filter, looks like a good idea mate.

Any possibility of a couple of clear shots of what you've done please? I'm sure others would be interested as I don't think this has been shown before here?

Its a sheet of ali fabricated to cover most of the bare engine and hold the crankcase breather. Sprayed black with similar pinstripes to the original air box. The crank case breather just fits directly to the original tube turned upwards instead of feeding warm oily air back into the engine (makes sense to have one but i may be totally off the mark). I'll try to get better pics of this. Also the strut brace is a nice tight fit downwards onto the prolex kit's right angled hose out of the throttle body so makes it more secure.
