What are peoples views on the necessity of having a cold air intake on a turbo'd car if the intercooler is doing a good job?

I want to run a single pass cooler on my Ibiza, but it would mean losing the air intake/scoop from the front of the bay, only con I can think of is the maf readings, but would this really make much difference?

Is there no way of relocating the air feed?

How necessary it is to have a cold air intake on a turbo'd car if it has a decent intercooler setup

Every car can do with a nice cool air feed into the filter to obviously try and keep inlet temps down from heat soak under the bonnet. Just relocate the air filter/feed if you're concerned. Surely its not that hard?

IMO, on a turbo'd car, the main priority of the air filter is to stop particles getting inside the turbo and fucking it. If its cold or hot air going into the turbo, it's no real biggie, the turbo is going to be running hot due to boost. Its the intercoolers job to cool the air down, and the air filter to, well, filter the air.

hot air is less dense so even if your running a really good intercooler its cooling less air than it would be if you had a good air feed as the air is more dense to start with

Can't get another feed in, hence why the intercooler needs to go where the feed is at the moment

I can't see the problem, as the turbo will be hot anyway, so the air within the turbo is going to be hot regardless of cold air feed. Aslong as the IC is doing it's job...

I think this would matter on cars running serious boost with serious power. The stuff we deal with I doubt we would notice such affects tbh.

My setup isn't ideal, I have a good intercooler with an effective shroud, but my intakes pick up too much hot air from the bay.

If you take in hot air, the average ambient is going to be higher than with a cold air feed. A guy I know had to have his car remapped after fitting a NACA duct as it flowed so much cold air into his turbo, it started running lean.

Basically you can have one of several combinations: cold air intake and badly ducted IC = warm charge, warm intake and cool IC = warm charge, but a cool intake, and well ventilated IC will yield the best results.
