Tr6's
 

How often should i change my plugs? I have about 6,000 on the tr6's in the truck now.

they'll last a long time, but it all depends on A/F mostly.

You shouldn't have to change them for 30 to 40 thousand if your tune is good.

There cheap though so it wouldn't hurt to do it moe often. :thumbsup:

I can get them for 1.80 a plug so thats kinda cheap insurance. My plugs always are white when i pull them.

if there white that is a little on the lean side, might want to have your tune checked out and your a/f reset
