Denso IW24 vs NGK BPR8ES
Denso is iridium($11.99 each). NGK is copper($2.24 each). Both are one heat colder than stock. Which one do you prefer/better for a lightly modified Evo(approx. 300 whp)? Also, please include the gapping. Thanks in advance.

for some reason my post got edited and some of it got deleted....dont know why 
but anyways...timing isnt bad as long as the engine is NOT detonating. The knock detector in our cars will hear knock and start to pull timing. So the timing advance that I saw made me think that the denso's range colder ran better than the stockers

I just made the switch from the stockers to the NGK BPR8ES.. I really needed new plugs. The car feels less laggy, has better response, and feels GREAT! The idle is much smoother once it is warmed up... Since they are 1 range cooler then stock the idle is a little ruff until the car warms up. But once it does it is like Buttah! After these I might try the IW24's but these feel great I don't see any reason to pay $11 a plug... They take 20min to install and so what if they don't last as long for under $2 a pop you can't go wrong! I can buy 5 sets of the copper plugs for the price of 1 set of IR.
