I searched an came up with nothing, My car needs plugs again and I'm thinking about giving them a try.

Thoughts?

 

Save your money.

The only benefit may be a slightly longer plug life and a noticably lighter wallet. Its not some huge triple spark going on, the spark will always travel the path of lease resistance and only arc to one tip at a time.

Plain old TR55s last ages in a good running LTX anyway.

 

dont do it! they r almost as bad as bosch +4s

 

I run them. No problems here...

 

Cheap spark or expensive spark their both a spark.

 

Don't get them!!!! Put a set in a buddies truck and 3 were cracked out of the box (no damamge to boxed whatsoever) and one completely quit working after 10 miles. Their quality is extremely shotty and I will never put a set in a vehicle I own.

 

crappy quality isn't the reason you shouldn't run these plugs.

 

But it's one of the many!!!! Given the lengthy time it takes to do a plug swap on an LT1 would you really want to have to change a random plug once it craps out after a few miles?

 

e3's are a joke!

stick to ngk's skippy...

 

HOLD UP ! I seen the guys on Spike Horsepower TV put them in a motor and they picked up 1 or 2 HP !!!!!!! !!! . But these are the same guys who put an LSX 6.0 LQ9 Iron block in a Camaro and Then went back an put the truck intake and accessories on it

I put 80K on a set of E3s in my Grand Am GT. Never had a single problem with them, this was after a set of NGK Iridiums. After 80K I have to say they looked pretty darn good, the "3" point system didn't seem to wear out as quickly as the it did on the NGKs (which only had 60K on them). Plus when I switched from the NGKs I got a lot of "butt dyno power" back. Engine was much more responsive. Granted this was due to changing the worn out NGKs.

The NGKs and E3s cost me the same (within $1) between the two brands.

However the 80K on the E3s were pretty impressively clean over the NGKs 60K.

Am I saying these are the best plugs EVVVAAAARRR. No. But I was impressed with the quality and how well they held up in the long run. It was enough that I bought a set for the TA and will put them in soon.

 

The shop I used to work at got sent a few sets of E3 plugs when they were in development. They wanted us to test them (dyno) on a few vehicles and send them the results. We saw no gain on any of our tests. Also did some fuel economy tests that yielded no noticeable difference.

 

uh...

 

E3 plugs are garbage had them in my Tahoe for about 10K before I developed a misfire. It turned out that 2 of the E3 plugs failed. NGK is the only way to go. IMO

 

Customers have brought there cars into the toyota dealer I work at and found the problem being e3 plugs. They put NGK IX plugs in and problem solved. They were throwing misfire codes.

 

i put a set in my 85 tpi trans am and it ran like crap
although my 97 impreza liked them quite well

 

there were these insanely expensive silver spark plugs TPIS had in their catalog years ago, run those, wayyyyy better than E3's
