[walt101786]

hey guys...i know that there's lots of threads on this topi...but i just wanna double check and all before i change it...well it seems like its time to do a lil tune up for my 07 HB...and what came to my mind is that i am doing some research...i am not sure which will suit me better...im looking toward changing my OE spark plugs to NGK irdium plugs.....and i know that they're great and all and i also know that Denso's iridium are great as well....these are 2 that came in my mind that i wanna go for, but mostly i might end up with NGK iridium one...but then i came across with Pulstar ones...i am not sure if these are good too....all im asking is that...by any chance if someone in here that are using it and if there's any improvement or not....just curious...wanna get ur feedback thanks
