Is there any problem with the coils in these overheating?

Would there be any benefit in moving them somewhere cooler or leaving the cover off?

the cover is there to hold down the coils onto the plugs. I wouldnt recommend leaving the cover off. First big bump and they would come off.

Nice advice. So they aren't screwed with bolts?

nope, there are little rubbers on the underside of the coil cover which keeps them down.

Check out a pole I did a while back, have to do a search for it.

I think they dont give much problem until you start pushing the turbo a bit harder.

More power more heat generated.

There has been quite a few coil failures.

Best thing to do is vent the cover so heat can escape.

When I build my new engine I'm going to look into a venting setup for it.

When my originals failed I fitted the set from my low K engine (Engine to be built).

I also purchased a new set for when I do ever finish the build.

Just think of heat as a enermy to electrical componants so, the cooler

they are the longer they will survive.

When doing any venting you need to make sure water can't enter or you will get

shorting and long term corrossion around plugs,head and rocker cover.

A simple idea is to run a intake hose into the cover, with the hose

running down the side of the engine away from any direct moisture path.

Then run another from the other end to the airbox.

The heat from it should not bother the engine air intake.

But if concerned it will run it through a smaller cooler core.

Other than that set it up with a vacume fan to draw the heat out so no need

to use the induction to draw it out.

Another idea would be to run a small catchment scoop in the bottom air intake grill but will

need to make some sort of moisture seperator.

If you decide to mount coil packs to a plate in engine bay just use silicone spray on them,

I have driven a old cortina through a flooded area where the water came over the tunnell

(Stupid thing to do when young) did not miss a beat.

Use to drive VW baja's off road and never a problem using the silicone spray.

Also great on marine engines.

Good advice, thanks

I wonder if the FG coils fit the BA/F engines..........they are apparently a bit stronger
