Just came across a really good deal on some Denso's.

What plugs do you guys think I would need for the mods in my sig. IT20's - 22's? I don't plan on extra boost. But probably just a chip and other mods in the future.

And no, I have no affiliation with the company, just tryin to save my brotha's some $$$ around the holidays. My truck is Idling like a B^tch in this cold weather....I'm hoping these will help

No Pulleys ??? Man your missing out
I'd go a range colder anyway, maybe IT-22's, they can be used with 4lb, 6lb, and with stock you would be assured a nice cool rich spark plug. Since they're known for the awesome idle and no misses I think it would be an excellent choice. Some may say go a range hotter ??? Get some opinions, the Denso's are great, (I use them), and that price is right.

 

Not sure about the shipping, cause I picked mine up directly from Sal of PSP (supporting vendor) for the extra $10.00

I have IT 22's that I got to try and stop detonation with a chip and 5 lb pulley I had. I could not get the detonation to stop with the chip and pulley so I pulled them and left the Densos in. I have a modified stock air cleaner with K&N and 170 degree thermostat. Plugs have been in for more than 15,000 miles and look good. Make sure you gap them at 0.040 and check for tightness every 10,000. When I checked mine 2 were loose.

 

If you are not running an aftermarket pulley and don't plan on getting one the IT 16 is the best plug for you but the IT 20 would be my next best choice. The IT 16 is the stock replacment but its not a Platinum like the stock plug so it will perform much better. The IT 22 seems to work great with any pulley you may want to put on later. Also with no added boost a gap of .044 should be great.

Thanks for the reply guys. I always get different responses. Usually a few say IT20, and others say IT22. I guess either one would do just fine. May go with the 22 just in case I decide to add more boost

Ran IT20s until I went over a 4# pulley. The IT22s were good with the 8# pulley. Replaced with IT24s and now running the 8# pulley and smaller upper and a 100 shot of nitrous. It is running great! (also running on the stock program, no nitrous)
