Hi,

I have been thinking of doing an alteration to the air box but was thinking of drilling a 3 to 4 inch diameter hole rather than lots of small holes, as some people have done, and installing a cold feed pipe to the front of the car thereby creating a positive air pressure in the air box and wondered what you think about the idea and do you know if there are reasons not to do it.

I have already had the car (2003 Skoda Fabia Elegance 1.9Tdi with 50,000 miles ) remapped (By Paramount performance) and thought the extra air supply would enhance the remapping

Any and all ideas and comments would be really welcome please, whether positive or negative, I have thick skin

All the best

I wouldn't personally bother, the turbo is going to pull the air in more efficiently imo.

I wouldnt bother either, as you'll be pulling hot air from the engine bay in (bad) vs cold air from outside the engine bay (good).

PD160 pipe gets more cold air into the air box

If your going to do, make it into a sticky id love to see how it turns out

Put it this way, putting holes in in itself won't be very useful. Some kind of CAI feed to the airbox might not be a bad idea, that will work hopefully.

i have visions of you drilling the top of the airbox,,, Ie after the air filter

if you want my honest opinion, i wouldnt even waste a second thinking about it..... pointless watse of time
