Hey guys I recently got my first lightning and hopefully soon I can get another cleaner one than the one I have . It has 170k miles on it stock besides American racing headers /exhaust and the K&N cold air intake kit . It’s been a good truck just recently had the plugs and coils all changed out . What else would you guys recommend me have replaced for this much mileage. I’m not a mechanic my self but I got tools and space to do fix a couple things my self and also I have a good mechanic I trust by my house . Any input will be appreciated .
