It took a little over a week for a large Honda dealer in Houston to order and receive my replacement spark plugs. And Ferret spot on, I believe they were about 19 bucks a piece. Plus install costs . . . .

I pulled my plugs @ 5000 miles to inspect. No re gaping no cleaning they were fine. Anti seize on the threads and back in. I will pull again @ 12000 miles.

FWIW: http://www.ngksparkplugs.com/pdf/dyk_5points.pdf

Quote:NGK spark plugs feature what is known as Trivalent plating. This silver or chrome colored finish on the threads is designed to provide corrosion resistance against moisture and chemicals. This coating also acts as a release agent during spark plug removal. NGK spark plugs are installed at the factory dry, without the use of anti-seize. NGK tech support has received a number of tech calls from installers whom have over-tightened spark plugs because of the use of anti-seize. Anti-seize compound can act as a lubricant altering torque values up to 20 percent, increasing the risk of spark plug thread breakage.

Wow, that's interesting

I change out quite a few plugs each year and never use anti seize, plus don't bother torquing the plug if you use it, you will not get a proper reading.

What's the best way to get to the inner plugs? I've got the slim socket...

1/2" drive ratchet and 1/2 to 3/8 adapter should put you below the frame and over the valve cover.

Use the factory socket.

Thanks for posting this. I thought I had all the spark plug sockets I needed. Glad Father's Day is coming.

Toro..do you have the one in post 1 of this thread? You can use a 13 mm box end wrench, 14 mm box end wrench or 1/4" drive ratchet I believe
