Sparkplugs for tuned Supra

[Echo_26]

Hey guys,

I’m planning to run stage 2 on E30 soon on the Supra and had a question about sparkplugs for that.

what’s the recommended NGK spark plug for a stage 2 Supra and what gap distance is recommended for running E30?

thanks guys

stock plugs stock gap. if you ever need replacements hit my site. Stock are the Champions. But if you prefer ngk... the "b58 one step colder" on my site will work.

I ran the stocks for 15k miles and then switched to Titan's plugs. Supposed to be a 1 step colder plug, but performance-wise I could not tell a difference.

Were they pre gapped?
what made you switch over? Long cranks on startup?

They are not one step colder for Supra or Gen2 B58. They are the same heat range as the stock Champions that came in your Supra.

They are only one step colder for Gen1 B58

Stock plugs all the way up to 700+

Cold plug guys probably have catch cans too

How are the stock plugs on the Supra? I haven't really seen too many posts about them.

Have run the stock plugs and gap beyond 850whp. No issues.

If someone is telling you to close gaps on plugs on this platform without an actual reason. It's simply because they read some old n54/n55 recommendations and are regurgitating that without any real knowledge of the B58 ignition system

they had a slightly larger gap than what the Supra calls for so i gapped them to OEM spec. I’ve read plenty of @Twisted Tuning’s posts and I still let the hype get to my head and used the colder plugs, stocks are perfectly fine and with 15k they were still in good shape.

my car ran e50 so I was used to long crank times. I switched them because I watch too much YouTube and got bored.

Another note: the plugs Titan sells are marked AG VW on the insulator. If you try and look for an NGK part # it almost looks like they etch it off. Kinda funny.

Unrelated to plugs. But you shouldn't have long cranks on e50 unless your HPFP is failing or the tune isn't adjusted properly.

My car sat a lot with e50 in the tank. Just my observation.... If I drove it daily it fires right up, if it sits for a week it did crank a little longer.

shouldn't matter how long the car sits. Shouldn't have a long crank unless the HPFP is failing, car has some ignition hardware issues, or the tune needs work. my car starts up immediately everytime. And im in NY on E90.
