I wanted iridium spark plugs for their added HP performance, I was the told the part number was: BKR5EK, and I bought six of them at around $5 each off their website, please let me know, thanks!

 

Iridium Plugs do not add horsepower on a maxima

and to answer your question

As long as I control the sticky posts, only NGK plugs will be recommended for Maximas......and Iridium isn't likely to make the last until I see some real proof, which I haven't.


The updated Spark Plug post in the Maintenance sticky has everything you need to know about replacing the plugs........













Why people insist that a spark plug gains several horsepower over another still boggles this brain......at least on Maximas...

 

i am still curious as to how SteVTEC said it gained hp on the Accord..

i would like to know certain factors .. were all the plugs gapped the same? was the dyno on the same day? how many dyno runs did they do?would any of the plugs by chance not be the same heat range? I am still curious as to how they can see a 6hp increase on a dyno with plugs..

I mean a car can dyno 10 - 20 hp difference with different heat range and also a car can dyno 6 - 10 hp on the same day with the same modifications..

i am still baffled

 

Me too.....and seeing as how you've had experience with Accords I figured you would have been aware of such gain potential....

 

when i had my accord i didn't even know how to change the oil
