Cold Range Spark Plugs?
#1
Time for new spark plugs?
In a couple weeks I am going to be begin the mods by installing a 15% pulley, bora cat back, cold air intake and the computer reprograming. Should I put in (correct me if i'm wrong) cold range spark plugs? I thought i saw somewhere that if you were to install a reduction pulley it was a good idea. any thoughts?

Cold Range Spark Plugs?
I will soon be adding a 15%pulley, Borla Cat, Cold air intake and I thought i read somewhere that it would be good since I am added the 15% that I get cold range spark plugs, does that make sense. please correct me if I am wrong but thats what i thought i remember them being called, thanks!

I ran my pullied MCS with stock plugs for several months then switched to IK-22s and both work fine. No real difference I could detect.

I ran a month with stock on the 15%, but put in IK22 more so cuz it was recommended by randy, cobra websites, M3 webistes, etc. Did I notice a difference in whp or torque? hard to say haven't dyno'd with them. I put them in with the screamin demon coil and live wires from Mossmini. I did notice it fires up at the hint of turning the key.

Your almost correct
Colder plugs won't stop detonation but will help prevent it. Since timing is controlled by the ecu, unless you have a bunch of carbon build-up that would increase compression, plugs are the most common cause of detonation. You'll not hear any pinging, the ecu will retard timing by, I believe, as much as 11 degrees. That equals a big loss of power. With all the money I spent on pulley, intake and exhaust to make more power, damned if I'm going to lose that power to save a few bucks on plugs. My .05(inflation

I ordered the Beru plugs from Outmotoring.com. They were $28 plus shipping. I know it's not as common a plug as the Denso IK22, but reviews I found seemed to indicate they are a good plug.
