So I thought I would have a bit of a play with my stock air box and intake to see how much cool air I could get in.
Liked the idea of opening up the snorkel but I just used one support on each side and a bit longer to open it up more.
Left the cover on where the "powerduct" would go for that stealth look.
Then I took to the inside of the air box with a die grinder to get rid of all the ribs and smooth it out for better flow (maybe).
Also removed that resonator chamber that just unclips and covered the opening with some aluminium sheet and some self adhesive foam.
Cut a 76mm (3") hole in the bottom.
Got some 76mm flexible tube from Clarke Rubber and just managed to squeeze it down to the lower bumper.
It wedges in against the bumper quite well (didn't use any cable ties) and is far enough back that it hopefully won't catch too much water or bugs.
Finally, I removed that hard plastic tube from the intake pipe and got a Turbosmart 38mm BOV plug which is actually a bit small and nearly fell through!
I have since found a 44mm blanking plug from eBay and it fits much better (put the old hose clamp back on too).
Results? Not so much down low but definite improvement in mid to high revs. Lower rpm (50ish) at idle too but not to the point where it's going to stall.
Loving the increase in induction noise/turbo whistle (sounds like an F1 car, small capacity V6 turbo, screeching tyres, sideways action, I think the new F1 cars are all good!)
Now for an exhaust to make use of all this extra air!
