i was thinking to remove the plastic cover for better cooling...just wondering if anyone tried it already with results...
i use to have an altezza rs200,and 1 of the problems with the 3sge is the coils heating up resulting to failure (misfire) they concluded that the engine cover is keeping the coils too hot,so it will fail earlier than expected (specially in tropical countries),so what they usually do (including the TRD altezza) is cut the cover maintaining the cover for the timing belt,but from there on,they will remove it....

i hardly show my engine bay (and most people just look at the exterior nowadays) so if it would help a bit in terms of cooling,i wouldnt mind driving without it....

TIA

I removed the two plastic side pieces. Left the front plastic because it helps guiding the air to the intake. Kept my engine cover since I have vents on my carbon hood. This way any water in the vents will drained directly away from the electronic above the motor. I can really see the heat waves through the vents when stop at the light. So the vented hood works great. The grill is pretty damn hot to the touch too

what vented hood do you have? any pics?

He has the Seibon TSII vented hood, with the majority painted body colour. Just the vents are carbon.

Removing the engine cover won't help cooling under normal conditions. Under normal conditions, your oil temp never goes over 3 bars. If you are at the track, it will help.

Why would anyone remove any of the plastic panels and engine cover on a car you daily drive? Completely unnecessary unless you do full redline drives to your destination everyday.

All day; every day! Just because it's the drive to work doesn't mean it has to be boring

dont think its going to make a difference on the street or the track. Nothing that will register on the dash.

You could try removing the entire hood for cooling AND weight savings

Lots of things don't register on the dash. Only the bare minimum of information is supplied to the driver to avoid warranty issues.

The engine cover traps heat and suppresses noise. Removing it and opening the hood when not on track makes a big difference in time to cool.

I was thinking about removing it for an upcoming track event...so good idea then? Does it just clip on the top?

Yes. Just pull straight up and it will pop off the four posts holding it in place.

thanks Lobux . I'll try it this weekend at AMP !! So it just pops off with no blots or screw?? I have been allowed to run both intermediate and advanced groups in the same day because I always leave before noon ( I have kids ). So now I can run 3-4 sessions in a block where I would normally run 2 so quicker cooling will be beneficial . Thanks again bud
