Just wondering if there is a difference in the plugs or anything on different year model trucks. My buddy just took an air dog 150 off his 99 24v he said I could have it but don't know if it'll work on my 07 5.9 there is one number difference in the part number. Thanks for any help!!

 

They may be different but I think it is just the spring inside maybe? But I know the the newer ones from 98.5 to 04 are the same. And the then 05 to 2010 are the same. You could call Air Dog and ask
