So I have this set up but I'm using Bosch Plat +4 Plugs and it sais that I can run a bigger gap on my plugs. My questions is will I see any spark difference if I switch the plugs and open the gap from .050 to .065. I have been considering it but I'm not sure I'll see a differnce.

Should feel fuller...a little peppier..

So is it worth it to go grab some plugs that I can gap and swap them in instead?

i always thought u had to have the plugs at around .60-.65 for the SD..... when i get the frpp wires ima run my plugs at .55...

I'd personally ditch the plat +4's and the coil pack and wires. The stock setup is more then apt at handling 300+whp. Just gap the stock plugs larger like you want to do with the plat +4's, besides, plat +4's are not designed to be gapped.

Thats what I'm saying. Will it be worth it to buy new plugsd and gap them a little bigger?

Are you running a chip or anything that requires premium?

Go that gap on the stock plugs, they on FJ have reported good results with that gap and the stock coil pack. I need to get some nickle and dime crap for my car, god, how it adds up

not a chip but I advanced my cam timing for premium gas and then programmed my SCT chip also.

Advancing your cams does not require yuo to run premium, you more or less move your power band up, so, it starts up higher.

The sct chip, if it is adjusting your timing, then, you need premium. I'd like to retard my cam timing so my power comes on sooner.

get rid of those bocsh crap plugs and put in a normal plug you can gap, nkg's, or better yet motor craft platinums.
