Looking to change out my current spark plugs. Anyone have a certain type of plug they like to use. I'm not sure which ones to get to improve gas mileage, if all possible.

 

Ngk!

 

I prefer the simple NGK copper V-power plugs. ZFR6F-11

 

Any particular reason why you prefer the V-power over the others? How do the V-power types work vs. the others?

 

I haven't actually tried the regular copper NGKs in my car. I just use the V-power since they're OEM 4Gen Si plugs.

I should give them a try when I get a chance...

 

i really dig my NGK irriduim plugs

btw i tried bosch +4 platinum plugs and my engine ran poorly, i do not recommend these

 

brisk racing plugs have been running well for me. originally engineered for the lambo

 

The V-power plugs are less than $2 at Napa. Is there really an affordability/practicality issue at that price. The NGK corp site says the V-power has better has ignitability than their standard copper plug.

 

NGK Iridiums all the way. If not those, then I would prefer Denso Iridiums. Nothing else touches my motor. Also those are the only plugs we use at the shop I work at. Thats the only thing we put in every bmw, mercedes, jaguar, honda, toyota, nissan, etc....

 

NGK Iridiums, here too

 

Zfr7f-11

 

NGK, Honda recommend them for the prelude and thats the only brand i will use.

 

Anyone tried Nology Silver?

 

Why one heat range colder?

 

Nitrous, I have just been lazy to replace them with the 6's i have sitting in my garage....lol

Though helms does say that if you live in a hotter climate you could go to the 7's

 

*nods*

 

Bosch plugs in Hondas.... "suck cheesy ***** covered in animal cheese" LoL

I would only use NGK

on top of that, If you have the money you should use the OEM Plug, Which is Laser Platinum and about 11$ a plug x4

If you want to go cheaper, the Iridium NGK is a nice plug for about half the price. 7$

My h22 seems to run the best with the OEM Laser Plug.

 

nothing but ngk touches my prelude.

 

I'm sorry. but LOL for spending $44 on plugs. I'd rather spend $2 for v-powers that work just as well

 

You're right, The cheap ones do work pretty well.. However I'd at least get the Single tip Platinum.. they are around 4$ a plug.. Still pretty cheap.

The Laser Platinum are OEM in H22's... It's what came from the factory Honda. And not only that, my 44$ plugs will last 10x longer than your copper NGK plug. So keep laughin. I would just rather not change my plugs as often.

 

+1. All jokes aside. The Laser platinum's last longer, but also the have a purer burn. So thinking from a technical aspect. Once you get into the higher rpm's the v-power's will never perform as well or last as long as the Iridium's or the Laser platinum's. I have nothing but Iridium plugs in my 3 Preludes and I change my plugs once a year just by choice. I could go longer. When I pull my plugs out, they look great enough to put them right back in If cash is low at the time I get ready to change them. Think of it this way, YOU OWN A PRELUDE, you don't put cheap gas in your car so why put in cheap plugs........

 

So I thought about it hard what I wanted and listened to all your suggestions. I ended up with getting the NGK Iridium plugs. They were $6.99/each; pretty reasonable i would say. I took my old ones out and looked at them. All four plugs were white on the stems or tips. Is that mean there were worn out or is that normal?

 

NKG for the win

 

Thats pretty normal they are just burnt and old. The NGK Iridiums are a good choice..

I like em.

 

Good deal. Let us know how you like em'.
