Spark Plug Question

[thdrill]

I know there is another posting here about the gapping of the plugs but don't want to hijack it. Been looking to replace the plugs (and will probably regap to the 0.35) but in looking have noticed the multitude of options. The question I have is regarding the prongs (pardon the mini-stroke). Are two and three really better than just one, does it really make as much of a difference in the "burning" of fuel as they are pushing?

Thanks

I think most people will say that it is a waste of money.

I bought some of the bosch 4 somethings (can't remember the name) when I was a kid and installed them in 89 cutlass calais quad 4. I didn't notice a difference in anything except my wallet. $8 a plug for nothing but marketing.

I put the Bosch +4 platinums in my tahoe, and actually got worse gas mileage then before. I then put the OE AC Delcos back in and am getting great gas mileage now. Noticed a huge improvement in gas mileage, almost a full mile per gallon. You will pay extra for the OE plugs, almost $6 a plug, but totally worth it. GO WITH OE PLUGS. one of the few things I would say go, OE. and they are pre gapped.

The next question would be - platinum verses iridium?

go with the NGK TR55...and gap to .040

 

[tybardy]

yes.... NGK TR55s and gap to .040... anything else and your wasting time and buying into hype

decimal in wrong place .035 or .04

 

[tybardy]

.035 is used when you have forced induction, NO need for an 035 gap under normal aspiration

I figures as much. I was messing with you.
