I can not find these damn plugs for the life of me, auto parts stores can not even order them. How much are the plugs going for, where do you guys get them?

You need to look them up by the stocking number-7317. We have several in stock. Let me know if your local parts dealer does not carry them.

I've got them thru O'Reilly's. They are special order and usually only take one day to arrive.

Tried them first, but they said they can not order those. They could get tr7ix but I want tr8s.

I had the same problem 1st time I tried to order them. It's not listed as TR8 as it is a NGK racing plug. They need to order it under part#R5724-8, stock#7317.

Here is a part# list of the NGK plugs (LS1s on top right).

Like stated above, the reason why no auto stores could order them for you is because they are not known as TR8. Look up part number R5724-8. If you have aftermarket heads, you will need the same plug, but with a .750 reach.

Tr6 plugs are one step colder than stock. Tr8s are a pretty cold plug for forcedinduction.
