anyone try the new Denso Iridium plugs? They supposidly give more hp, and are beter than the platnim +4.

any reviews?

Hey Cisco, we were talking about this the other day, i never got a chance to finish. The reason Plat +4 plugs are no good for Bimmers is due to the ignition system. The BMW ignition system doesn't output near the voltage of a lot of American cars. Thusly, there is not enough voltage to utilize a four electrode platinum plug.

Unless you plan on going to an aftermarket plasma ignition system i would just use the oem plug .

For the last time and love of god. SPARK PLUGS do not give more HP. You need some help.

iridum plugs run too cold in our engines. unless you force the car , there is absolutely no benfit what so ever.

[Eggrolled211]

Had same dilema, I went back to bosch platinum+2, no more plat+4....learn my lesson......they suck!

[CiscoKid]

u like +2?

[CiscoKid]

i might actually try copper, they burn out quicker... but its not like they cost an arm and a leg

[Eggrolled211]

Yeah bosch +2 copper are the OE replacement, I know they don't cost and arm or leg but I don't want to replace that often atleast a year or two etc. Unless you have lots of time to kill. I'm meticulous about my car but I'm lazi too! hehehehehe

[CiscoKid]

well... fortunately for me... i have alot of time to kill working on my car (unless i get a call from the lady friend, but i usuually make her wait until im finfished working on my car)

[CiscoKid]

im going to go to my grandmas house, but on the way back, im going to puck up some new plugs and scrap the +4s.... what about NGK?

[jllphan]

I don't know man, I would probably go back to the oem plug, if you wait a little while i will post a picture of 'em. The reason being, you won't find them at autozone, i tried. So i will show you what to go "hunt" for. The tech i talked to made sense, he said these cars are pretty well tuned, and when you start
f@#$knig around with them, you usually wind up with adverse effects. ghead

[Eggrolled211]

I had all the same questions like you etc. exactly and many others...I mainly see NGK for imports etc. BOSCH and BERU for European cars...I just stuck with OE requirements thats Bosch!....Stick with +2 bosch copper or platinum...not +4. Choosing the most efficient sparkplugs will give better spark,fuel economy etc. but it doesn't give you HP!!!

Never buy NGK, their very inferior sparks. I had installed these in a car I had before, and one of the sparks went broken while I was driving. The ceramics parts had damaged the cilinder totally....

Buy what eggrolled221 said: Bosch

i found a place with the iridiums.... what should i do?
