im probably opening a can of worms here, but i just wondering if anyone has used them?, im using them at the moment and i know a few others that are ,

the main person i no has been using them for over 5 years has done lots of drag races on different boost settings and NEVER! had any problems with them at all, we no they need to be changed more regular than the originals but for the price of them you can change them a fare few times before you reach the cost of the oem plugs,

 

ive not posted this to cause any arguments just wanted to no peoples thought or if you've tried them :)

 

cheers wayne

sorry i see a simular thread about something simular to this , so i guess its already been covered :)

I use them as i believe they are better if youve upped the boost.

 

I change them every 1000 miles which at the moment is about once a year!
