    E3 spark plugs

    I am looking to do a tune up on my 06 wrx this weekend, and am curious if anyone has used the E3 spark plugs. They're supposed to give a better burn increasing fuel economy and hp. I would install them on a n/a vehicle in a minute, but not sure if they are the right thing for my wrx.

    No experience with them, but I do feel confident saying that OEM spec ignition components will win, hands down, every time. Your WRX LOVES to advance timing when it can, and it's tuned around OEM spec spark plugs.

    Like you, I'd wait for "the other guy" to test these out first.

    Is there a plug on the market that doesn't make the same claims? That'd be the plug I'd want to see, since that would be the plug that's truly unique. Everything else increases fuel economy and HP according to the makers.

    Why? Sorry I'm not following the logic.

    To me its a different set-up. Not as much going on in a n/a car as there is in a turbocharged car.

    I've got them in my Jeep's NA 4.0 straight six. Its got the old cap and rotor style ignition system and a 50kV coil. They did help smooth idling a bit. They also claim to increase HP, increase fuel economy, and reduce emissions by burning the fuel mixture more efficiently; claims I can not verify. I personally dont think they were worth the $6 a plug.

    I would say go OEM, that way you know that you have the proper plug for your vehicle. I pretty much use OEM spark plugs in all my vehicles (distributor and plug wires may change, but always OEM plugs).

    If you are getting a tune any time soon, NGK one step cold plugs will increase horse power and economy, but don't use them if you are not going to tune for it.
