Appreciate your advice on the gapping but wat is it about my wheels?

They are 17" by width 8.5" & offset 25.

 

lol... the chrome

it was a joke. They are definitely nice wheels. Not sure i'd like the chrome, but its not my car, so who gives a ****. I bet you are happy with them, and i'd imagine they look good on your car.

 

If I'm running 24PSI, spiking at 26PSI, should I run the Densos one step colder?

Mods are:
TBE Exhaust w/ Downpipe
Walbro Fuel Pump
FP Wastegate Actuator
BR Intake
ECU Tune

Made 379whp/353wtq on Mustang Dyno, which reads like a dynojet.

My car didn't start misfiring till I put on the Testpipe, now it has a loud POP whenever I'm in 3/4/5 gear and slam the gas to the floor. Its fine till about 5.5-6k, and then POP. I'm guessing I should go one step colder? I'm on stock IX plugs with 18k on the car.

 

Ive always worked by the 1 stage colder for every 100hp or so over stock.

 

So I should order the Denso IKH24. What should I gap them at?

 

I'm wondering about the gapping of the IKH24s also. Should it be gapped at .022 to .024 or .032? Densoiridium.com has it as .032 that's why and idk which to go with... Lmk whoever knows, Thanks I appreciate it.

 

I had issues till I gapped these plugs to .018-.020 depending on power. I really also like the HKS m40il plugs. they are not denso made like the s40il. THey have a larger electrode .6 instead of .4. Good luck they are 67 a set shipped from thepartsbin.com

Gap to .024 like stock recommends.

 

I have a great guy that I order the IKH27 plugs from, 45.00 :-) PM me if you are interested in getting some. KEVIN or e-mail me at k6031@yahoo.com maybe if we buy in bulk we can get even a better price. I have already used one set all good and such. great plugs.

 

up we go

 

out of curiosity... arent the IKH24, 27, the same price and cant you get them for about that price from spark plugs.com ? I know i havent paid more than 11 or 12 a plug for them.

 

IKHXX's should be gapped to our specified gap. They come pregapped at .032 from the manufacturer. I have always regapped them to whatever the cars mod level is. Anything on meth i gap tight at .021 to .023, not on meth but modded .024 to .026 nothing bigger.

 

Is there a huge difference between the NGK 1-step colder and the Denso 1-step colder? Or just the big bop in pricing? I need to change my plugs, but I can't justify ~$150 for those NGKs.

 

hey guys,
just a quick simple question, sorry
I have a evo 9. can i use this for the 1 step colder?
