Plug & Wire Upgrades. Thoughts?


Recommended Posts

I'd like to install new wires and plugs in my 91 Legacy for better mileage and/or acceleration (when I need it), but a few questions....

[*]What brand wires & plugs should I use?

[*]What kind of gain should I expect, such as high-rpm or low-rpm increase in HP?

[*]What about a new coil-pack? Do they even MAKE performance coil packs?

[/list=1]

 

Thanks for the help guys & gals!

Been through a number of different brands and models. I have settled on Bosch FR7Dx. FR78x "Super 4" don't agree with the DIS.

 

Cables are OE, but only two years old.

 

Cold air intake? Surely the car had this already? Legacies I and II suck air from the right fender. I trust you mean that you have removed the "intake resonator"??

In a matter of speaking, I removed the filter box and replaced it with a Cosmo Racing cone filter. A lot of cars do not follow the "cold air" idea because they worry about mainfold icing, so the pre-heat the intake air. :madder: Stupid idea. You get more power from MORE DENSE cold air! Anyway, it's just a bigger intake than that little hole on my filter box. Legacy777 had said he made more intake holes on the bottom of his airbox, and this worked out as well as a washable filter. Guess I should have read this before spending the $30 on the new filter :-P Oh well, it looks better than the filter box did :brow:

as was said

there are no real gains to "upgrading" plugs and wires on your OE car.

 

if you have the OE engine... what is the point?

you wont see any gains.

 

save the $$ and put it elsewhere....

bet OE plugs/wires which were DESIGNED for your car

and make the car run RIGHT.

NO hiccips

NO hesistation issues

(these can be found with the inappropriate plugs/wires)

 

most discount subie stores offer these things cheap!!!

(ours is 30% off retail!!) that's the route i'm going...

and that's my $.02 and change :D

 

cheers

Is there a difference between Subaru OEM wires and the wires you can order directly from NGK? Does NGK make wires for Subaru? It looks like the OEMs from the dealer cost much less than the NGK when you order directly from NGK. I checked couple of dealers in our area and they are charging exactly the same....
