Another spark plug question...

With my current mods, what spark plug do you recommend? I was thinking Denso ITV22, due to the positive reviews and the fact that they are pre-gapped to the stock height (~0.30), but I wasn't sure if I need a one step colder plug with my current mods. The problem with the Denso ITV20 which is standard heat is they come pre-gapped at 0.44 and I am concerned that I will break them trying to get them gapped to 0.30. Has anyone had success re-gapping this plug to 0.30? Do you recommend I just go with a one step colder plug? BTW..I have 32K on my car if that helps. Thanks in advance for the help!
 
ITV22s should work great for you. Double check the gapping when you get them, though! A couple of mine were not gapped correctly.

No problem. What you're looking for is something like this:

You should be able to pick it up at any parts store for less than $5. Use the wire half-loops to check the gap and then use the notched ends to gently bend the electrode as needed. You're aiming for between .028 and .032. I gapped mine at .030 (if I recall correctly).
