4.6 engine H.P.
My stock 08 F150 4.6 engine puts out in the neighborhood of 150 H.P.
If I add custom tunes, a K&N cold air intake and maybe high flow pipes what could I expect to increase the H.P. to?
I do not want to do any major modifications to the engine with that in mind what is the most I can increase the H.P. with out doing any damage to the engine.

My K&N cold air kit cam with a dyno sheet. Stock form it stated our 4.6 puts down 188 rwhp. After installing the cold air, rwhp bumped up to 198. I hope this helps out.
