NGK TR5 OR NGK TR55 spark plugs
Hi everyone;
Well, it is getting close to new spark plugs, and I believe the only difference in the 2 plugs is the gap. The TR5 is a .035 gap, and the TR55 is a .050.
Which plug would be the correct one for my stock 2001 Z28 (lid and cat back)?
Thanks in advance.

Thank you all so much for the input, I am going to take it that "NA" stands for Naturally Asperated", which is the catagory I fall into.

TR-55's here, too. Please, please remember to check the gaps before you install them! I only had one in a set of eight that was right on out of the box. Don't trust the stock gapping!

whats the benifit to running tr55's over the iridium plugs? I hav ealot of detination ive noticed on warm days and im in canada so a warm day is like 35-40 degrees wich equates to 95-113 lol. I was thinking if i could find a cooler plug then the iridium (currently running) then id use them but if the tr55's arent any different then ill just stick with these and detune some i guess ...

Iridium's actually make a slightly stronger spark. When they were updating our store for the new NGK "ULTRA IRIDIUM" or whatever their rep came in with a little display that actually showed the spark capabilities of iridium and copper and the iridium was a little brighter and a little larger.
However, I don't think that makes a difference unless you have a really high performance motor or a smaller (four or six) cylinder. IMO.
