Can anyone help me out with a link? Yellowbullet used to have a good plug cross reference, but it doesn’t open up anymore for me. Use it ngk r5671a7 plugs now. I need to find a slightly shorter plug for clearance with one tube on my new headers. Thanks.
NGK makes a short one. That's what I had to put in one of our cars.

Curtis in the accel plugs is a larger number a hotter plug? The ngk plugs I use are “warm” according to them. Kole do you know the part# for the short ngk plugs?

Man I'm not sure. I run the same plug you do. I jsut quickly tried to find out the heat range on those and didn't see it but I didn't try very hard. Sorry.

It’s all good. I will see what I can find. Should have checked the fit of new headers better before I had them coated.

Accel heat range 4 is the same as NGK heat range 7 (see chart in link). The shorty plug is part # 0414S-4. This shorty plug has a resistor in it (probably 5k ohm) that I believe is normal for these plugs. This is a projected tip plug.

I think it's like 3035. I ended up calling NGK when I was looking for shorter plugs and they helped me out. They were great to deal with on the tech line.
