Looking for a cheap 21 mm spark plug wrench.

My deep sockets were too thick to fit in the hole. Harbor Freight doesn’t carry a 21mm and really not much on eBay or Amazon..

Anyone, know if this will fit?

Kurt,

buy a cheap-o socket and take it to a bench grinder and grind it down. I do have a tool set I got from costco as an emergency set (Made by Crescent). It has a spark plug socket that fits without grinding. Set was $100 ($80 with coupon).

 

Use the one in the Tool Kit in the rear.

 

Kurt--

Plugs are 13/16". H-F sells a set of four plug sockets sizes in swivel-head (5/8" - 3/4" - 13/16" - 7/8") for about $10, and the 13/16" fits in the S4 covers OK. Got it to do James' car (16V) which is a little more forgiving on size, but it fits the S4 too.

For the S4, I have a H-F tool that has a permanently-attached extension on a slight swivel. It's a perfect fit in the plug holse. I haven't seen them lately at the stores through. It's perfrct becuas it never leaves the socket in the cover on removal.

 

Thanks for the suggestions… that should do it.

I was wondering if those ‘standard’ spark plug sockets at HF freight would be good enough. They don’t carry any metric spark plug tools.

If I had the tool in the rear compartment, I would have used it… ended up borrowing one from Brett’s car to get them out.

I wanted to have something in my tool box to use and only have fairly expensive craftsman deep sockets not worth trashing.

If this doesn’t fit… I’ll grind on it:

""""only have fairly expensive craftsman deep sockets not worth trashing"""""........thats funny.sears is where I buy tools to heat and beat on

 

OTOH using a quality tool to make a new version isnt such a bad idea as they will probably be stronger than a cheapo socket thats been heated and cut only to shatter due to junk steel

 

Kurt,
I have an elcheapo socket in my hand as we speak that fit without any mods...changed all my plugs a couple of months ago. The cheapos are a bit thiner in construction I assume.

 

FYI use a 13\16 socket...works fine on our plugs and fits in the hole on the cam cover.

 

Great timing… HF put these on sale this week…. More shinny objects

 

I will be purchasing a set also... this is a timely thread for me.

 

Looks like you need a lot more that a spark plug wrench

 

Nope, that's it... going to put the whole car back together with used spark plugs and 13/16 bolts.
