Talked this over with ts86net and The Mighty a while back and finally got round to doing it myself.
This was done on the 2.0 20v engine, it should also work on the 1.6 & 1.8. The diesels have a similar layout but I cannot guarentee that the noise levels will be tolerable. Not sure about other engine layouts but it is fairly easy to check.
This mod is so simple and gives so much in return that it is hard to believe it.
The induction system consists of a moulded combined intake/radiator fan guard, rubber intake pipe, plastic elbow joint and the air box/filter.
When ts86net and I had a look at the elbow we both realised that the end that joins onto the airbox is larger than the end that joins onto the intake pipe. So by removing it we would be allowing more air to enter the airbox.
First unplug the rubber intake pipe from the top moulding and elbow. No clamps on mine, but there may be on yours.
If you then take the top of the airbox off and remove the filter you can see that the elbow is just clipped into the box. You can remove it by squeezing the pipe by the lugs and pulling. This does not damage the elbow and it can be replaced in about 10 seconds at a later time without having to take anything to bits. Put the filter back in and replace the airbox top.
Plug the rubber pipe back onto the top moulding and you now have a cold air feed.
Now go for a test drive. I find that you can only just hear the difference on idle and when cruising but that it really ROARS on acceleration, ts86net and I both think that the mod sounds great.[8D] ts86net says he gets more power but I have not had it on long enough to be sure yet. I am going to fit a K&N replacement panel filter next which will release a few extra bhp though.
I may also fit an extra cold air feed pipe from the front grill to just below the airbox. You just have to keep it approx. 4" away from the inlet incase you scoop some water up.
If you try this and decide you don't like it; then it takes about 30 seconds from opening the bonnet to closing the bonnet with the mod reversed
Please feel free to comment on this post and let us know if you have tried it yourself
