It has come time to replace my spark plugs, but I can't seem to find any good comparison of spark plugs. The guys at Auto Zone have their opinions, but I really don't feel they have the proper knowledge to give me the right answer. What spark plugs have you guys hadd the most success with?

NGK, and Bosch platinum...

 

The reason I had to change the spark plugs is because the relatively new Bosch Platinums I have are beginning to misfire. I never did like them except when I first bought them. For a while, I had problems with the plug wires I had coming off. No more Bosch, and I would like to find something better than OEM.

 

And that's all I've ever had in my car. lol I think I've had better luck in that aspect than you, though.

 

NGK

 

bosch +4 plugs dynoed for more power.

its been posted before...

 

zex sphark prugs suit me fyne.

 

zex plugs blow axelzzz....

 

Tru y0.

 

I dunno about the Bosch plugs, since they are misfiring. I know that everything else is good, so it has to be them. I was looking at finding something different.

 

Bosch plugs suck on Hondas. NGK or ND are good.

 

..... my head hurts... how can a bosch plug dyno for more power than NGK and suck?....

 

One dyno run can vary from another by 2hp real easy. That doesnt prove that the Bosch P + 4 added any more power than the NGK's.

Anyway, I'm on +4's now too because they were free. They improved my idle.

 

Ive seen too many Hondas towed in because they wouldn't run, and all I had to do was replace the Bosch plugs with NGKs to get them running. They may work in some engines, but in others they totally suck. I wouldn't recomend them.

 

same here bosh platnum they freaking last forever

 

You should get NGK Irridium for 6.4 a peice.. Go to http://www.sparkplugs.com and your parts # should be bkr5eix-11

 

My interest has been piqued

 

i just use oem ngk plat.

they work great for me.

 

I thought the OEM NGK's were copper

 

maybe so. they work fine for me either way

 

Does anyone know where to get Nippon Denso's?

 

coppers are superior to iridium and platinum in all aspects except durability... get a set of ngk coppers properly gapped and in a heat range suitable to your setup and change them regularly. They're cheap so that's not a problem and its easy to get at plugs to change them.

 

Denso Iridiusm plugs.

 

i've seen a dyno where ngk's gave more power than the bosch plug..depends on the application you are running. cant seem to find the dyno plot though.

i use ngk's they work fine for me... they're cheap so just replace them every 15k miles or so.
