just use a combination of a adapters, I did that and attached a small ratchet with a breaker over it easy peasy

I know easier way, bring it to a dealer

We used a 3/8 to 1/4 reducer and a 1/4 inch ratchet but were still too weak to break it loose, still in there! Which reminds me, I should give it a try again.

There are tons of options when it comes to adapters /extensions, etc. But the SK 45159 3/8" extension is supposedly the "magic" key.

Yep. That and a regular ratchet.

For my NBS I picked up a wobble extension set from HF and used the very short 3/8" drive extension: https://www.harborfreight.com/search?q=67971, 61278

And a skinny arm or two...

Regular spark plug socket + 3/4" short socket on the end. It is just the right length to extend beyond the manifold, but leave room to get a regular 3/8" rachet in there to bust it loose.

On my 2004, I spent 5 to 10 minutes removing the tin heat shield and access to the #8 spark plug was a breeze. I am not sure if this would be the same on a 2007 to 2014.

just did mine on my 2010. do it with engine cold in the morning. i found it hard to remove wire so i bought special curved needle nose plyers and reached thru wheel well over top of tire to pull it off. then just kept trying different lengths of extensions and my ujoint adapter. the pass side of the engine took me 2 hrs. the driver side took about 10 minutes!

This. Standard tools found in pretty much any tool kit. I think people overthink this.

Most people don’t have a 3/4” extension.

New ones are easiest from below. Just enough space to reach up there and get it with a socket and your hand.

Neither do I. But, what does a 3/4" extension have to do with anything?

It’s the best way. Regular plug socket with a 3/4” EXTENSION on the end, which Im pretty sure @Hi-psi meant:

Or maybe not but a 3/4” extension with a regular plug socket does work best.

I've always used a 3/4" regular (not deep) socket on the back of a 5/8" spark plug socket. This probably ends up being about the same as having a 3/4" extension. But, most any mechanic's tool set that includes a 5/8" spark plug socket is gonna have a 3/4" socket before having a 3/4" extension in the assortment.

Never heard of that one.

I wouldn't BS you!

Just measured: My Craftsman 5/8" spark plug socket is 2 3/8" long. With a Craftsman 3/4" short socket on the back of it, the combined length is 3 1/8". All 3/8" drive.

I just checked, same here. With the 3/4” extension instead of the socket the total is 3 5/8”. Either method will work so now we have more ways to do it. With my headers though on The Beast I now have to pull the fender liner and go from below. But on the Silvy I can still do it from above.
