Yea I was wondering if anyone had any thoughts about the E3 plugs vs Pulstar Spark Plug Iridium Pulse? Or if there is a better one out there?

Don't get either. Either get stock replacement plugs if you need them, or get a set of NGK TR55's and set the gap at .060".

E3's and Pulstar's are not good replacement plugs for the 3800. When buying spark plugs, you need to get plugs with the correct heat range. The two you listed could end up harming your engine and they will not improve performance.

 

To add to Zipper's comment, I changed the plugs on the '05 Impala my wife and I go during December (car had 150K on factory plugs, just seemed like a good idea). With what we bought the car for, I was not a fan of spending $7 a plug on AC Delco Iridiums. I took a shot on NGK platinums for about $3 a plug.

Taking out the stock AC plugs, the stem had AC Delco stamped on them, but the metal banding about the fitting had NGK etched/engraved in them, just like the new NGK's I was putting in (made me feel better, knowing the beloved AC Delco, OEM plugs are nothing more then re-branded NGKs).

Food for thought. In general, I stick with AC Delco plugs on my GMs. The Impala is the first in a LONG time I did not stay AC Delco. But now, I feel some what comfortable with NGK's knowing Delco uses them.

 

x3, forget getting special fancy plugs- OEM equivalent plugs work just fine- just stick with platinum or iridium and you'll be fine.

 

Im running e3s and i have one cyl missing i think it might be the plugs, and i had another problem when i tired em on my s10.

I have also tried ngk iridum and i ended up burning a hold threw the cylinder.

Used AC delco plugs for years without any problems and good performance.

 

First off thanks guys, much appreciated. I looked at the NGK's and found some, but neither have both of what u said. one is NGK TR55IX IRIDIUM IX SERIES with a 1.5 mm gap and the other is the NGK ITR4A-15 LASER IRIDIUM SERIES with a 0.06 gap, not the TR55 though

I got mine for the Impala (3400 v6) from RockAuto with other items I needed (they had AC Delco wire sets on sale at the time for $12). I got NGK Platinum plugs, I believe Part #3403 (TR55GP) GP-Series Platinum, currently $2.31 a plug. And did that mid-late December 2010, and the car is still running great, I have ZERO complaints!

I believe my local parts stores stocked those NGK plugs, but due to the other items I was buying, it was cheaper (even after shipping) to use RockAuto.

 

With spark plugs, you have to gap them yourself. It's really easy to do though. If you go to a place like Autozone, by the cash registers's you'll find a spark plug gapper. It kind of looks like a coin that goes on your keyring. Whatever plugs you go with, make sure that the gap is .060".
