I normally use the stock BUR plugs is stock engines outputting stock power levels and then for modified engines with porting and above stock power levels I use EGV racing spark plugs. I have seen that a lot of second gen guys and third gen guys use these plugs and I was wondering if they good. I just heard about them and whats awesome is that they have a 5/8 hex head on them so I wont need to use my thin wall socket to get them in as I had to do with the EGV racing spark plugs. I would like to get reviews from people to see how they are and if they are good. Reviews would be great not for me only but for any others that have the same question as I do.

Thanks Adam.
