You could easily get 13hp from new plugs...but it's a trick.
First I take my old plugs that were in my car (63k miles), lets say I gapped my plugs incorrectly, and made it a VERY small gap. This would cause a VERY small spark, and very little combustion in the chamber. Plus being and old plug, the spark wouldn't be as good.
Now I put in plugs correctly gapped that are iridiums. All the sudden there's more power. It would be easy to gain 13hp this way...it's a trick basically.
Another way...in HIGH HP engines...like 800hp...different plugs can easily make a 13hp difference. Now in a 300hp engine? You might get 1 or 2hp from them.

Atleast that's what was recommended with my old car. It's a pain in the *** to replace them on the SC300 or any 2JZ-GE engine. You have to take off the throttle body to get to them. I recommend doing compression test while there. The place where I am going to get won't charge me extra for compression test. Cool, ain't it?

Then you will be able to extract the extra hp with your S-AFC too... Are you doing a dyno run with the s-afc off then with it on? Also is the traction off or on in a dyno and the ECT on or off? Just curious about it...
Also your wires, cap and rotor could be in the need of replacement... They will make a huge difference if they are bad too!

PS. When are you coming down here again Tom? We're having a meet on the Dec. 1st. and Alex and this other Tom might show up for the dyno of my car this weekend on saturday.

Good luck on the dyno this time around...

so wiz, are you saying that I would get about that much HP gain since my spark plugs are 80,000 miles old?
BTW, has anyone had these plugs longer than 6oK miles on their car and was the performance still ok? Or does it last just as long as any other platinum or conventional plug?
