FWIW, I just did this. I expected it to be easy given my experience working on cars. I wasn't disappointed. Very easy. I did not have to remove the battery at all. Easy to do with the battery in place, IMHO. Also, there was a comment about going 1/4-1/2 turn past finger tight. Mine were about 1 turns past finger tight in order to crush the washer and get to a good tightness.

Also replying to this thread because I think it is a good thread for noobs. Thus, it's now back to the top

FWIW guys,

They do make a tool to straighten radiator fins out. Go to harbor freight and you can pick one up for cheap if you have a store by you. It also has multiple sizes for fin thickness variations.

So I take it the coil pack towers clear the cylinder head when removing them. From the looks of it, it looked liked the motor would have to be lifted a few inches to clear the uni-body to remove them. Are the coil pack towers rubber & flexible? No one had issues w/tweaking the heck out of them w/out lifting the engine?

You dont have to lift the engine. Trust me (I made this DIY). You might have to use a flexible socket knuckle to hit it at an angle though.

Gotcha, so how did the coil pack towers clear the cyl. head? Flexible rubber? No issues w/tweaking the heck out of them to get em out? I'm not worried about getting the plugs out, just getting the coil pack towers off w/out damaging them. The majority of imports I've worked on have hard plastic towers. Thx. When I looked under the hood, I assumed the engine would have to be lifted a few to get the coils safely off.
Thx for the post.

I know this post is terribly old, but just for the sake of it... just yank them out. They're made of flexible rubber and it won't damage them.

I did mine today for the first time and it wasn't nearly as bad as I thought it was going to be. It wouldn't have taken me long but a buddy of mine were working on it and taking our time hanging out.

One tip if it hasn't been mentioned yet... if you've got the type of spark plug sockets (Craftsman) that have a rubber boot in them make sure to pop the boot out when you insert the new plugs. It's much easier to get the plug socket out when it's not stuck to the plug itself. I can't imagine trying to get the socket out with that rubber still in place.

Glad to see that my thread of almost 2 years old is still helping people. Thanks!

Yeah, and thanks for the post! It certainly reduced the "ugh I don't feel like doing this crap" factor when I could see in pictures that it really wasn't so bad.

It was nice knowing that it wasn't going to be anything close to resembling the pain of replacing the spark plugs on a V-8 f-body.

also on those Plugs they are good for people who drive on Freeway's at about 85+ MPH you dont need a Turbo upgrade for them.. if you drive fast on the freeway it Could be benificial... it's Textbook about spark plugs.. good write up cheif.

on stock cars.!

[higB_0x05]

i just did plugs on a friends Legacy GT. What a pita. ... the passenger side was a breeze but the plug nearest the driver was a nightmare. luckily ive done the plugs on my wrx and sti before... but there is virtually no room at all on the legacy gt... you're flying blind for most of it. Not a snowball chance in hell in getting a torque wrench in there.

HVAC tool called a "fin comb"...wont work on a TMIC, but will work on some radiators, transmission coolers, power steering coolers, and oil coolers.

Nice right u man made it a lil easier for me

[chaos311clarity]

why are they recommended? reduce chances of detonation?

[effect]

i would hafto check my textbook i got a whole chapter on why or if you even need to run colder or hotter plugs.. all i remember for sure its better for your engine if your always speeding on the freeway to run that colder plug.
