A Largely pointless excercise unless you are tuning the absolute nuts off of it.

That's one - I think typical one used to be cutting off the standard trumpet just at the front edge of the intake manifold.

Provided the rain guard (a recall and fit item for early cars) is fitted it's absolutely fine for 99.99%.

No - no difference in itself.
Why? Because it makes more intake noise ? who knows what goes in for real in peoples heads?

Doing the intake mod on the diesel does absolutely nothing, niether does fitting an EGR bypass.

The diesels have more than enough air going into them even when tuned.

We've tested all at one time or another on the same car and found it makes no difference whatsoever.

Can't blame anyone for fitting an egr bypass to save having to clean it out but it doesn't have any advantage over disabling the standard one

Just clean out the egr and remove the little pipe , push a small bolt into the end, then wedge it into the little gap near the tube that you pulled it from. Then the egr will stay clean.

A cold air intake makes no difference when you are feeding the air into a turbo, which is bolted to the exhaust manifold. Hence that's why the intercooler was invented.
