Thinking of trying a drilled box with K&N panel filter, can anyone tell me :-

o what the increase in noise is like ?

o is there any noticeable improvement in performance ?

Thanks... <img src="/forum/images/graemlins/laugh.gif" alt="" />

Drilled Air Box isn't good for performance, noise of torque in low mode

you will have just a good sound <img src="/forum/images/graemlins/laugh.gif" alt="" />

how about the 57i

I have the drilled box with K&N panel filter on my coupe. I haven’t noticed any loss or gain of performance. The main change is the noise which is fantastic. <img src="/forum/images/graemlins/shocked.gif" alt="" /> Not too loud but a great sound when you put your foot to the floor. <img src="/forum/images/graemlins/ooo.gif" alt="" /> I got a drilled box off the forum in case I wanted to put mine back on. Realy easy to fit.

Go for it <img src="/forum/images/graemlins/wink.gif" alt="" />

I read in the old forum someone describe it as 'Darth Vader in your glovebox'.. I don't notice that it's much different from standard if your gentle on the throttle, it's when you push on, (as people have said) it makes a nice growl. Your recirc DV (if you still have it) will sound a little more like a dump to atmos one too.

To me it felt a little less torquey in the midrange but seemed to pull slightly stronger at the top of the rev range. Hope that helps. <img src="/forum/images/graemlins/smile.gif" alt="" />

I noticed a bit of a drop in torque low down the rev range when i did mine. Lovely sound - but not as nice as a k&n57i/Darth Vader! <img src="/forum/images/graemlins/laugh.gif" alt="" />

Ok cheers guys..will give it a go I think ! <img src="/forum/images/graemlins/smile.gif" alt="" />

MCMike - try to get hold of an airbox that has been drilled by someone. That way if you don't like the sound you can always put your old airbox back on. <img src="/forum/images/graemlins/smile.gif" alt="" />

I think i saw one on eBay earlier.

you can always repair it with gaffa tape later. make sure its sticks well as you dont want to suck it into the filter

Im sure a new airbox (the lower part) is only about £10 from fiat anyway so give it a go <img src="/forum/images/graemlins/smile.gif" alt="" />

Personally I wouldn't waste the tenner. As Leedscoupe said, you can always tape over the holes if you don't like it, job done <img src="/forum/images/graemlins/smile.gif" alt="" />

I had this mod before - nice sound, lost low down torque slightly though, so I just taped the holes up again. I also noticed when I did this that the car became a bit smoother to drive again
