I just added Denso Iridium Power Plugs (IK22) with the .4mm electrode to my super charged 03 V8 Tundra. Denso references a dyno test on a 03 super charged Mustang where HP increased from 300 to 330 horses. They say the plugs add only 3 or 4 HP to a normally aspirated motor. I’ve never seen much discussion on these plugs so hope to get your feedback. They cost $11.75 each but I changed them myself so no labor charges.
Also, any ideas on how many horses I actually have?
Toyota says 240 stock
TRD says +50% so add 140
TRD says 10 for the TRD exhaust
Estimate 30 for the IK22 plugs
Total 240+120+10+30=400
I do not want to overstate the HP so I ask if anyone can give me a better estimate, I would appreciate your input. All I know is the truck is very fast and very fun to drive.
