Intercoolers, per se, are not illegal. A manufacturer will emissions certify a vehicle based on the requirement to meet certain pollution standards. To change that vehicle means there is a likelyhood of changes to the pollution emitted. This is why there are laws relating to tampering with pollution controls. In the case of intercoolers, these have the capacity to alter the amount of air entering the vehicles engine (by the fact that it cools the air - increased air density) and this in turn can affect the mixture entering the cylinders. Yours sincerely Greg Howarth "Andrew D" <the_pornstar@ho To: [email removed] tmail.com> cc: Subject: Re: Your request for information from 12/03/2003 05:06 EPA PM Hello greg Thanks for replying to my email just a few more questions i have i currently have a vl turbo and they were not factory fitted with intercoolers I heard that avo intercoolers are legal and can be fitted but they are very expenesive but i have seen people advertising in the trading post that they custom make intercoolers so i was wondering if they are accepeted by the epa. Also why exactly are intercoolers illegal i ask heaps of people and none seem to know. Thank You Andrew Some original photos have not been recovered yet.

Remember that VLTs do have a factory intercooler as per GM manual.

yep.. the fins on the cross over pipe is GM's idea of an intercooler Some original photos have not been recovered yet.

It could be nissans idea of an intercooler and telling holden to put in there manual for the car...Since nissan gave all the details and specifications on the motor in the first place. Just a thought Some original photos have not been recovered yet.

so i guess boost, 3" zorst, cooler and cold air ram together make my car EPA unroadworthy.... i guess i'll keep that crossover pipe incase i have to put it back on ever.

I just dont see how an EPA inspector can take your car off the road. I mean even if a car is worked with crazy mods, if the car passes the original '86-'88 emmissions standards, then it is a "clean car" and therefore should not be taken off the road. I know should be and reality are two different things but Im hoping these pricks gets dragged through court one day and lose, thus setting a precident for modified car owners.
