Todd/Proto does not like Denso IK-22's, he had me swap them out for OEM plugs gapped down to .025.
His take was they work for a short time and then misfires.

 

Thanks i'm going into to BBI this week for a set of there catless pipes so will suggest the plug swap ,also found out i already have a mafless tune from Todd/Proto .

 

Great, unplug the MAF's and you car runs on MAFless tune plug them backin for MAF based tune.

 

i have a set with 100 miles on them. free if u want them

 

I'm listening ruf. So it's fair to say stay clear of the Denso IK 22's then. So what are you putting in next or are you going to perservere with the Denso?

 

There's nothing wrong with Denso per se, just my ignorant choice of IK22. Todd now, and Mike before him, suggested staying with the standard heat range. Denso PT20's are going in when the rest of the mod's are done.

Someone else mentioned that the IK22's didn't last very long and that was my experience. The car felt pretty good when I left AWD, but within weeks (and maybe 500 miles and a day at Sebring), I started getting the stuttering and stumbling below 4krpm.

 

We run the NGK iridium's on most packages.

 

What's the diff b/w the maf and mafless tune? Does the car run any differently? So you don't have to physically remove the MAF, just unplug?
I think Todd/Proto said I had a MAFless tune but I'll have to check.

 

Neil, do you stay in the same heat range or go colder?

 

What EVOMS installed for the 775

 

What's the plug number? PT20pr-p11, PT20pr-p8?

 

INTERESTING
Very nice thread i was about to open one this morning what a surprise.
im running what todd sent me and i feel like its time to change them car started to cut abit in high rpm high boost !
i believe he uses for my set bosch gapped spark plugs !!

 

evoms like to use pt20pr-p8 both my turbos (996,997) love these plugs

 

I pray they aren't IK 22's ed. Im sure they are not.

Neil how do these price up against the stock and the good Densos? Pm me if you don't want to make pricing common. I take you've tried the Denso's and the re gapped oems and frond the NGK iridiums to be better? How many K's before they are over their peak? Do they go for longer or where are they better in your experience?

 

great thread
