Question Spark Plugs and Wires?

Hi,
I want to get a set of performance plugs and wires. I would like any recommendations on what companies and what sizes to use.
Thanks
Steve

Magnecor wires are great. I don't know that you can do much better than the stock platinum plugs. They're NKG's, if I remember correctly.

If you have a MY00 & above, you can definitely do better than the stock plugs (Champion coppers ). Plug wires won't do anything except make the engine compartment look pretty.

Good question. Ask Subaru.

I know there has been many disappointed RS owners including myself at finding Champions under the hood.

hey folks, i need some help here. but ill offer up some personal experience too.

Spark plugs and wires only make a miniscule improvement (or damper) on power depending on what you opt for.

Magnecors are Great, especially the BIG wires like 8.8mm or even 9mm. 8mm is practially OE replacement, and 7mm isnt any better either.

Ignition upgrades should really be the Last step in the search for power. cuz they dont do much improvment for a stock EJ25. but if youve got intake, exhaust, cams, chips, or any other combo of mods, youll Definitily have an improvement. ignitions are basically complementary upgrades.

i wanted to put an Ignition box on my 7, but held off cuz it wouldnt really do a damn bit of good unless i mess w/ the air and fuel system.

i saw the ad for Direct Hits plug wires and capacitors. that looks very promising. Anyones ever use them? cuz i think i might like to get some of them.

I have heard that the bigger Magnecores aren't needed, its only extra insulation.

Yea they are bigger, but they sho is cool, aint they! hehe

so, in simple terms;

Magnecor wires either 8mm or 8.8mm...9mm might just be over kill like previously stated

Torque master plugs, give them a try. after all, they DO have a racing history, and patents, just like magnecor.

stay away from Sp*it-fire, thats basically a fad item. and stay away from anything Else that you might think falls inline w/ Sp*itfires. cool? hope i helpd more than hinderd

FWIW, I just put on Magnecore wires, and the car starts and runs a bit smoother when the motor is still cold. No power difference, just smoother. And no its not in my head, I can tell the difference with my car especially since its not a matter of power.

Nope, no thoughts on the torquemasters, none whatsoever. I haven't even heard of them to be honest!

Denso Iridium plugs...
Denso as in "Nippondenso" now that should be a familiar name under any Japanese car hood!
Fire power of a copper plug, and the longevity of a platinum plug! Best of both worlds.
They also utilize the patented tapered U-Groove tecnology that Denso has built it's reputation with.
NGKs are real good plugs, however Denso plugs are better!
A set of 4 $60 shipped anywhere in the US.

Unhappy

the better question is what type of spark plug you should get not the wires. The stock wires are fine and even work for up to 8-9 psi boost. But the sparkplugs should stay as oem as possible. There is not need to spend 200+ on a setup on NA for any reason unles you inclrease conpression.
I say it's a waste of money on a Stock impreza (intakes exhausts don't count either.)
