I was wondering which plugs do I need to be running in the car. I have patriot ported 243 castings along with a comp 232/236 595/601 XE-R.
A-4 with full bolt-ons and a 3500 stall..........................................
I live in Mississippi where it is about 50-60 degrees in the daytime right now.
I have the AC Iridiums in right now, but they are fairly old plugs.

Thankyou,

Brent

Heads are not milled and the compression is around 10.7 or 10.8

TR5 from NGK would be my suggestion.

I would suggest either a TR5 or a TR55IX plug for that motor. You want a good clean burn.

Ngk Tr55

tr5 and tr55 is not the same plug-right?? In that case what is the difference in them. Heat range?

Im running the TR6 plugs with about 11:1 CR. The higher the number, the colder the plug. The TR5 and TR55 are both the stock heat range, but the TR5 is gapped at .035 and the TR55 is at .050. I gapped my TR6's to .040 IIRC.

Is the tr55 ix a iridium plug?

The IX suffix means irridium. The standard TR55 is a copper plug.

So, which would be better............the regular tr55, tr55 ix, tr5...............I want a plug that would be suited for the summer also...........summer here is around 95-100............maybe I could just adjust the gap for the summertime.

TR55s are what I use and change them every 20k miles. If you are spraying go to a TR6.

go with TR6's with that cam/head/compression combo
