I got them from ORiely's. Who ever said $9 each, well, there smokin' some good stuff. They retail for $5 per. But I had a coupon and go them for $4 per. I've run champions and accel U grooves. I did feel the difference in that the idle felt smoother. That's just my opinion though. I'd buy them again. Hope that helps.

 

I used these

I like them.

Also the I've heard good things about the champion truck plugs.

Or just go with the stockers. They're just sparkplugs afterall.

 

Thanks for the input guys. I have been interested to find out what the recommended plugs were for these engines. I have a 1000 mile one way trip to take in a few weeks and want to tune her up before I go since we all know how they get awesome fuel mileage.lol.

 

I've read many reviews on the E3s in various engines since I saw that J415 recommended them.

In various cases, they seem to improve MPGs in most cases, and decrease ETs slightly. Even in the people that rated them 3 out of 5 or so, they decreased ETs, and the reason they were rated mediocre is because they seem to lower MPGs in 4-bangers sometimes by about .5 MPG or less. ("I am now getting 84.7 MPG rather than 85! They suck!") Silly little cars.

My local O'Reillys doesn't carry them, but I have an Advance Auto store close that supposedly does. $6 a piece. I think I'll give them a shot next oil change or so, see how they compare to the Autolite 3923s I currently have.

 

I was gonna get the 3923's for my setup. Maybe more people will run the E3's and I'll have to change my mind
