Well, I did it anyway! Nice and easy, took about 15 minutes start to finish, including knocking up a heat shield. It sounds wonderful now, but on light acceleration you wouldn't know there's a difference.  On WOT it sounds spectacular!

Hmmm What is the acronym WOT ?

I imagine that you'd need to change the filter every two months given the dust that flies about in an Engine bay.

That must be fire retardent foam wrapped around the Air box etc? 

I always thought that warm air from the EGR valve is better to get engines up to temp, so unless you blank this off, then it perhaps wouldn't make any difference doing the mod? 

For a street car in the winter you'd be pushing freezing air in most of the time.

I've never red lined my car to hear if it makes noise. Still waiting for my ECU to return from the States so can't test it. Not sure I will any way.

Interesting though.

WOT means wide open throttle.

The colder the air the better. Colder air is denser, denser air = possibility of more power.  Although this mod is more about surface area and lack of restriction than cold air - it gets cold air anyway.

The EGR valve is for emission control - nothing to do with getting an engine 'up to temp'. Engines need cold air. 

Yes the filter will need changing more often. 

I'd imagine you won't be able to redline your engine anyway - the VVTi system has probably never been exercised in its life so it probably won't make it that far up the rev counter!

Make sure you clean the cobwebs out from under your accelerator pedal and continue to enjoy your LS 🖒 😉 

 

Different strokes for different folks.
