I put my Denso Iridium plugs in today... replacing my relatively new Bosch Platinum 4's. No real noticable increace in power... maybe a little more low-end grunt, but nothin significant. It seems to idle a little smoother... maybe I can get a couple more MPG out of them.

Anyone else have these? how do you like them?

 

if you car is vtec, the bosch might cancel out the vtec from kicking in. I know it did that too mine. Now got the ngk vpower plugs. I here the vtec;o)

 

???? ?????

How did the Bosch do that?

is there a difference in any of the iridium spark plug brands? i noticed some are f*cking really expensive

 

can a spark plug cancel the vtec from kicking in?

 

Unless i upgrade my COIL,I am not going to waste $30+ on plugs. Most 6gen come stock with Plat. plugs which last up to 100K same thing with Spake plug wires they can even make you lose power I am not saying your wires will last 100k only the Plugs.

 

I have a MSD distributor and coil...

Anyone see the price on the HKS Iridiums?? $20 A PIECE :jawdrop: :bs: :screwy:

 

well bosch are known to suck in hondas so it doesn't surprise me. remember the manual does reccomend ngk or denso plugs. also +4 are platinums which suck and the +4 is bs, since electricity follows the path of less resistance. which means it's probably only flowing through one of those prongs.

i suggest trying the stock ngk coppers.

 

yup. it comes with ngk platinums...but i think you're supposed to change them at 60k no matter how long it lasts, but i may have to check the manual again.

whaa? who the hell puts copper plugs stock? i think that ferrari modenas even drive over 2000 miles without changing the spark plugs.

 

in a 94 accord stock plugs were copper. platinums are used today simply so honda can say 105 or 110k before you change your spark plugs.

do a search and learn something, platinums are not for performance, but longevity. real racers stick with ngk coppers and change them every 10-15k miles.
