No coil boots/dust caps for the 4.7?
Hi all. Long story short, my engine got wet from a car wash. No problems until hours later when I went to start it. I got a p0302 code, so I stopped and picked up a new coil. I jumped right to the coil because I've had this on again, off again loping/stumbling idle problem at start up without ever giving me a code. I figured it was from moisture and that the boot was cracked or defective. I pulled the boot and found it pretty went. I also pulled the spark plug but it was fine, however the socket was also wet. I ultimately replaced the coil anyway but not before comparing the too parts. The new coil has a some kind of a dust cap on top that fits over the spark plug well. Not one of the other coils has this. I was temped to replace the other 7 just for this, but I don't want to spend $130 just because of the dust cover I never knew about before.
Firstly, were factory coils installed this way or did someone in the past remove this dust cover?
Secondly, is there really no sort of "boot kit" for these coils that has the dust/water cover?
Thanks.

Yeah, I thought that at first, but there is a "groove" on my other coils where the cap sits on the new one. I'm not even sure these are all factory coils either, I'm the third or fourth owner.

yes there are boots for the coils.I have gone through enough coils to know this. Probably what happened is someone changed out the coils, When they pulled the coil out but the boot stayed on the spark plug. Unfortunately you have to get that off so the socket will sit on the sparkplug right. It is P.I.T.A ! They probably didn't want to go through that again and left them off. You found out why they are there the hard way. You should be able to go to autozone and just by the boots. I know they sell them at orielly auto parts. GOOD LUCK!

Anyone know of a third party company that make a plastic cover that covers the spark plug wells on the 4.7 like those one many of the newer LS engines? I would love to have something to keep all the water and junk out of the spark plug wells..That sure would cure a lot of problems for us.
