I just bought some NGK iridium IX spark plugs for my GSR n/a. People on other forum told me that these spark plugs aren't good for the vtec motor(performance-wise) Do to the low heat.

Can someone tell me which spark plugs are good, I have been told NGK laser platinums are good for my n/a GSR. Any other comments on that or other suggestion on the SP that I have already bought. Don't want to install them if they're gonna grain on my performance.
