looking to replace the stock spark plug by DENSO ITV22 as Cobb suggested,but couldn't find any retailer that carries them.I checked some websites in USA and the shipping alone is like 50% of the items($20-$25):complain

I can get these. $15.50 per plug + taxes. Now when you say $20 - $25, you realize that's the price they're quoting is per plug right?

I've got my own source for Denso's in Canada, so a lot quicker order time than through SU. However, if they get better pricing I'll order some through them.

performance was very small but still a bit noticeable. the car seems to run smoother

as for install it took 10min for me cuz i dont have the TMIC anymore so it will take longer for people with the TMIC

Hey Pat, what's the gap size on the Denso plugs?
mleblond

you have to set it when you get them

I read somewhere that they come .040 or .042 stock. I'd have to check though to be sure.

yep you need 0.38 or 0.36 for stage 2 cobb?

Cobb recommended 0.026 ~ 0.028.

From M3F.


I just put some XP5263s on yesterday and they seem ok. I went 0.010" under the spec, for a gap of 0.040". I would have gone with 0.042", but my gap tool is in 0.005" incriments. I'm thinking Cobb's recommendation of 0.026-0.028" is specifically for the Densos which are normally gapped at 0.035". This is a difference of 0.008" which is the recommended maximum change from factory.

With Iridium plugs, you can't apply gap specs from one plug to a different plug. Take the Densos for example. The center electrode is 0.4mm, where as Autolites and Bosch use 0.6mm electrodes. This will change the characteristics of the spark, which is why Denso recommends 0.035", Autolite 0.050" and Bosch 0.044". Back in the old days, a gap was a gap, but not with Iridiums.

I believe the reason Cobb recommends closing up the gap by ~0.008" is to decrease the chance of spark blow out, as seems to be a problem with our cars, as evidenced by the coil spring stretch trick.

This is straight from Wiki:
narrow-gap risk: spark might be too weak/small to ignite fuel;
narrow-gap benefit: plug always fires on each cycle;
wide-gap risk: plug might not fire, or miss at high speeds;
wide-gap benefit: spark is strong for a clean burn.

According to Sparkplugs.com, going beyond 0.008" deviation will change the geometry of the relationship between the side electrode and center electrode. This is why you shouldn't "crush" a 0.050" gapped plug down to 0.030".

I've talked to Jimmy and the GM mechanic there and they ARE DEAD SET AGAINST re-gapping iridium and platinum plugs...I think Cobb (one of their guys) cautioned about gapping your own plugs as well...but of course, DECREASING the gap is different than jamming a gapping tool in...pls correct me if I'm wrong as I'm interested how you guys are decreasing the gap...

Give me some copper plugs...but then again, I'm not on Stage 2+...

I originally put my NGK's in at stock gap, and when running Stage 2+ I was getting hesitation in 2nd through 6th. Gapped them down to .030 and went away.

All done with a gaping tool from CT.
