Pulse Plugs
 

Well, I've been running Pulstar https://www.pulstar.com/ plugs in my Cavalier for a while, and they haven't done diddly. In fact, I seem to have suffered a loss in MPG. I do have a worse commute to work since Feb of 08, but if I run the numbers it looks like I'm down around 2 MPG. If I get a chance this weekend I'm going to throw my old NGKs in and see what happens. :mad:

I had the same experience. The OEM NGK's were better for me.

Yeah, that was a hunnert bux I coulda spent better. Even if just to buy a few extra tanks of gas.

Results were too small to notice in my testing of the Pulstar plugs as well in my VX. I had a set of the "First Generation" ones and suffered a little bit of idle quality. They worked well while I was testing Near Wide Open throttle (NWOT) driving with my car though.

DKjones96 had stated that they found an idling issue with the first design and have since been fixed.

They've actually changed quite a bit electrically and physically within the last month or so. They're easily 4 times more robust now than they were before and 5+ times more than the 'first-gen' that I believe everyone here got. They took my advise on the internal resistor so nobody should have any idle problems or anything anymore.

Actually... anybody running these PM me your info. Lets get them changed out. Let me know if it was an actual order or if they were comped.

My car runs OK with 'em, and I didn't see any problems with the idling characteristics. I also gapped then according to the manf. requirements. I'm just disappointed with the fact I saw no gains in MPG.

Yup, better to stick with OEM regular or platinum. I got a 1-2 mpg increase just by changing plugs when the originals were worn....replacing OEM for OEM.

If you use platinum plugs use a plastic gapper so you do not scratch the thin platinum plating off.

Just my opinion.

I think platinum plugs are not supposed to be gapped at all, they come pre-gapped and say "DO NOT GAP" on the box.

They say that because the electrode metal is so brittle. Iridium plugs are the same way; you have to be VERY careful when gaping them but it can be done. The ground strap is usually plated copper or something similar to that so it's fine to bend.

If you have a soft touch with normal metal feeler gauges you'll be alright. Just remember to adjust then try to measure and don't force the feeler in much at all.

Really? for my Cressida they were like putting new plugs in replacing worn to heck ones except I already had new plugs.

you have a PM dk. I've got a box of goodies for you too.
