Default Removing Plastic Engine / Coil Covers



this is not a how to question but a why question. (i am referring to the big plastic covers that say "LS3" on them)

do some of you guys remove them because you can't stand the look of all that plastic covering your engines and you would rather see the coil packs and valve covers? or maybe because it will allow heat to escape from around the coils keeping them cooler and help create a better spark?

i plan on getting some nice valve covers, MSD Coils and fuel rails when i add the new FAST 102 intake but until then i was wondering about above.

tks, dal

I removed mine because when I added a FAST, they did not fit properly. I believe some have trimmed them with a dremel to get them to fit with the FAST.

My understanding is that they are there mainly to quiet down injector and valvetrain noise. I have not tried running my car with them removed to confirm this though.

I've had mine off for awhile now and been complaining about valve train noise. I guess I'll put them back on and see if that works. If so I'll be back to a happy camper unitl the next thing comes along to bother me.

I'm going to go out on a limb here and guess that your removal of those two plastic pieces has a LOT LESS to do with valvetrain noise than your hot cam and associated stiffer valve springs does

Both reasons, though it is not going to help spark, and they do look gay, very gay

When I start doing engine mods I will remove mine. I like the look of the coil packs and a nice set of vavle covers.

Modern engines are nowhere near as "pretty" as the old muscle car bays used to be. Today's engine bays are so loaded with wires and hoses routed all over the place, it's just a mess. The engines are not on display so the covers give some sort of style to what's going on under there. I do love the look of coil relocation and powdercoated valve covers though. Unfortunately they're a little more expensive than leaving the stock, or even painted aftermarket, covers on. As for performance, heat, sound.....I don't know how much of an effect they have.

Man that's always a dead give-a-way.

I just went out and cleaned the engine, Blowed dried it and put the covers back on. All pretty now.

I removed mine since I do not want anything that would retain heat in even the slightest fashion in the engine area. As insignificant as they are I want heat escaping as efiiciently as possible.

Does the "toupee" on the intake manifold serve the same purpose? (noise reduction)

You can make an engine bay look old school with a few extra $. This image is from Gotcha.

I trimmed my fuel rail covers so that more of the hardware shows. I'd rather see nice red coil packs than a big ol' Tupperware lid on my engine. I mean if you don't want to see the hardware, why open the hood in the first place?
