Thread: New pulstar sparkplugs ??

Post # 22 Wjere can I see more picture of yer 33 Hemi ? It looks awsum...quench is missing in any Hemi or dished piston.This is the coolest part and provides some turbulance so you probally are correct,but,I am not an cylinder designer and other who frequent these pages can offer much clearer advice.

Post # 17 Every now and then someone does a oil filter study.Cut open and comparison.Fram are always at the bottom of the list in quality.Time after time out of many.Was a post the other day on www.bobistheoilguy.com about seeing a guy in Walmart buy a Fram filter and 5 qts of 10w40 motor oil.The guy watching this was curious to what dinosaur these items were going in.10w40 oil is real old school these days and does not do well in oil...

If Chrysler engineers thought that they could meet emissions/power standards with a single plug of a specific design instead of a dual plug, don't you think they would have done it? If a better plug puts out 10HP, then they detune the engine on the top end, and use the added efficiency...

Post # 23 Quote: Originally Posted by 33hemi It is my understanding that two plugs were put into the head to create turbulence in the cylinder to improve atomization of the fuel and improve mpg. It was a relatively cheap way to make the improvements, without redesign of the head. Dual spark plugs are purely for emissions, to establish two flame fronts for a more complete burn. There is really no performance advantage, but it is a fairly easy...

Post # 14 I use Autolite as well. If I go Platinum which I will, I would use the Autolite Platinum plugs. I put them in my last ram. I've never had problem with champs myself but I have heard others state what you have. I guess its all a matter of preference. I just can't see spending the money on some of these other plugs on the market that are so expensive.

Post # 2 I've never noticed an increase in performance with plugs......just stick with what Mopar gives you IMO

Post # 19 I always use NGK plugs in my 700hp 4 banger. Almost all other plugs I used would only last 2 - 3 weeks tops until I would get break up at high rpms. In my old 4.7 durango, I changed the plugs and put in some platinum plugs. My wife started to complain about some jerking about 6k miles later. Took it to the dealer since it was still under warranty. They said it was because of misfire from the plugs. Plugs are not covered under...
