First off I want to thank MrLM7 for his post regarding the free mods that you can read here: https://www.truckforums.com/m_11160/tm.htm .....

Just last night I installed or modified the 4 things he discussed, except for the exhaust becuase I already have flowmaster 40's installed and dumped. I also went ahead and baught a k&n filter while the air lid was off. With that being said I am extremely impressed in the gains that i've recieved just buy spending 35$ on the filter, and another 5$ on a hose to bypass the coolant, and also a few hose clamps. All in all 40$ for a pretty noticeable gain.

I would recomend doing these for anyone that hasn't already.

 

Thanks for the shout out...
