has indexed their spark plugs!?

 

not i, what is that? lol

 

<--- Curious too. What's that, like keeping track of the location of your plugs?

 

Checking that the gaps are rgiht I think. I did it on my last motor new one needs a tuneup pretty bad. Ill do it before I resmog. I failed terribly

 

I have. They have those gap tools (don't know the proper name) at Autozone for about a buck.

 

i do it every now and then

 

NGKs are pre gapped

 

but you should always check them cuz you never know.....

 

i do :fawk:

 

Indexing is not gapping.

Indexing is pointing your spark plug in a certain direction to maximize horsepower. In many applications, this involves pointing your spark plug at your intake valves, but some apps make more hp with the plug facing the other way.

Good for about 1% horsepower gains on a built motor if you're lucky.
