[s-cars] Cold Air Intake

[tony.curran@sympatico.ca]

The stock air intake is very restrictive as per article previously mentioned. Also the plastic pipe is heated by the turbo, it is sucking in warm air, snakes around engine caompartment and is comparatively narrow. Also at mid-point of the hose there is a cross brace inside further restricting air.

I implemented an intake hose modification. It was previously done by another lister but I don't believe a write up was ever wittem. Cost in parts is about $25us. Parts are readily available from stores that sell clean room type products. Here in Canada Busy Bee Tools has them.

Original hose is replaced with approx one foot of 4" diameter flex hose attached to the oil cooler air intake snorkel. Mod took me about two hours. Need to remove passenger headlight and unfasten the oil cooler.

Engine sucks! Accelaration is improved (seat of the pants measurement). I have MRC stage 2 chips which are designed for 22 PSI - I've peaked at 27 PSI with mod. There is no evidence of water from rain spray making it to the filter.

Also, as stock intake is no longer in place more cool air passes over turbo - turbo is running at lower temp by 3 or 4 degrees (this I've measured).

E-mail me if you want to see pics.
