2008 Astra XE
Default Re: Looking to buy an Astra

Thanks smwalker, you've been a great help.

I checked the GM dealer beside my work and they gave me a price of $20 per ACDelco spark plug... umm... no thanks.

I've been trying to get information on NGK plugs, I don't want anything fancy, I just want something that will work sans gimmicks, something comparable to OEM is fine as long as it's not $20 a shot. Any suggestions?

NGK's US website lists just one, IFR6W-7G which is a Laser Iridium plug. NGK Canada lists ZFR5F V-Power, ZFR5FGP G-Power, ZFR5FIX-11 Iridium, and PZFR5F Laser Iridium. I don't understand the inconsistencies and I don't see a point in going to an iridium or even platinum plug, my understanding is the OEM plug is copper, so I'd like to stick with that.

I should have pushed a little harder to get some more out of them, but overall I'm happy with what I got for the price.

You'll have to speak up, I'm wearing a towel.
