How often should they be changed??? I have heard as early as 5-10k.

Also i made badass easy wiring for my bottle heater. I took a old lighter plug splitter and pulled it apart and wired the bottle heater to work of a cig lighter plug...simple and easy

 

I don't know. If you're running nitrous..I'd be checking them probably once a week or once every two weeks..

Nitrous does strange things to plugs sometimes..better to be safe then sorry.

 

thnx

 

Depending on your a/f ratio you might need to swap them every 5k or maybe 10 or 15k. I change mine once a year regardless or if I melt a set which has happened.

 

ok i'll prolly swap mine out before the meet....there only 10bux so it's not like its breaking the bank

 

With a solid setup there should be no reason to not change more then once a year. Unless of course you melt a set.
