Pulstar plugs

[deserth3]

I put E3's in my 06 H3. They melted down at about 5000 miles.

I had a friend of mine whose a mech talking to me about these a few weeks back and has them in his truck.. Loves them too! He ultimately said if you really didn't like them that pulstar would buy them back from you. Just some food for thought!

That's true. Their website says that you can return them if you're not satisfied, 30-day guarantee.

If anyone plans on changing theirs on there alpha have fun with the number 1 plug drivers front. I almost gave up an left it in there.

Yep, that sucked. The idle seems a lot smoother. Now the evaluation begins.

Just curious as to why you specified the I5. Would this not apply to the V8 as well?

Different ignitions. I5 has coil on plug packs, V8 runs conventional muti-coils with plug wires.

No intent to burst any bubbles. My brother-in-law had the assigned task at GM's Tech Center (Warren MI) a couple years ago to dyno run every kind of spark plug they could find, the fancy expensive newfangled "U" grove, split tip, multi platinum.... the list goes on and on. They pulled 100s of loads on a bunch of motors. If they do anything, it does not show up on the dyno, not even a tiny bit. The purpose of the testing was to provide engineering with data to decide if a certain spark plug would improve efficiency enough to include that particular plug as OEM, or incorporate its design into an new OEM ACDelco plug. They weren't looking for just more power, that was only the part he was working on. They were looking for burn efficiency as well (emissions and potential fuel economy).

The results....... the envelope please..... the super duper special plugs are nothing but a marketing ploy.

Materials are important to longevity and reliability, but a spark plug is a spark plug.

Personally, in an I5, I would run nothing but OEM because of the high intensity spark from the coil on plug packs can chew up lesser electrodes (E3s for example).

I agree 10000% as an ex-GM service engineer. However, there are those experts on this site now that know more than any engineer just by the seat of their panties.

One reason why I don't normally look at anything but the BS week threads....

And now I go back to waiting for BS week and ignoring all else.

And some people are arrogant, know-it-all, pricks with an attitude that think they have the right to talk to someone anyway that they wish.

As for the panties remark, I'll compare man creds with you anytime that you want, dick.
