opening spark plug gap?

[CrawlingEye]

have any of you tried opening the gap up a bit to see if it yields any positive results on your 5S-FE's (or other engines)?
I'm thinking about trying to open it up .004", as after a couple hours of research, I've discovered it's not suggested to open the gap up more than .008" so you may mantain parallel surfaces between the ground and electrode.

I think it's safe to say .004" should be safe, as I've heard of an na mr2 guy running a pretty hefty gap with his stock ignition system without any ill-effects.
I know this will not give tons of power, but I'm assuming it'll be about on par with advancing ignition timing (and is free).

Thanks.

wouldn't hurt to try

you 4bangers are lucky that it's so easy to get to those plugs....

yeah, I'll give it a shot in a month or so, I'll have to take the plugs out then anyhow.

I'm thinking that so long as the stock ignition can keep up with the gap, I should gain some power and mileage from it.

better wires, etc etc.

I have the NGK performance wires on, which from what I gather are sufficiently good for a high-performance ignition system.

I'll be looking just to minorly open it up (like I said, only a .004" increase to give it a .048" gap)
