Then how come I called up my local dealership, and after I gave them the VIN, they said my truck does not have air injection, or an air pump? Can someone please clear this up for me, because now I'm confused.

Also, I will probably be getting these pretty soon, and now I am debating on which ones to get, the JBA stainless steel ones, or the JBA silver ceramic ones. I have seen pics of old stainless JBA's and they're horrible. But I have also read that silver ceramics tend to rust also. The silver ceramics look a lot better, and run cooler, but I wouldn't want to spend the extra cash if they're going to rust either way. So please guys, let me know which ones you think are better.

 

Always go ceramic coated when you can.

 

Look under the radiator near the oil filter for the AIR pump. If you have it, it will be there. If not, there will be nothing there.

 

Ok, I will check to make sure, but I also just did a search on here, and found that the RPO codes for air injection are K17, K18, and K19. I do not have any of those on the white sticker in my glove box. Thanks again.
