Anyone run a bhaf and then upgrade to an afe stg 1 or 2 and notice a big difference? I'm still running stock but looking to improve what i've got. any opinion would be great thanks.... JOIN NOW TO REMOVE TRACER
I have dynoed back to back runs with a BHAF(Fleetguard filter)/Mallory Mount(thestainless steel heatshield a former TDR member made for us back then) and AFE Stage's 1 and 2.Both of my AFE's had the Mega-Cannon filter(or Inverted Top as they call them now) and the Stage 1 also had their 'torque tube" on it.
I seen little difference in Intake Air Temps between them all when checked and the AFE Stage 2 with the Mega-cannon out horsepowered the other two by 14 to the ground.The Stage 1 was 6hp better than the BHAF and the BHAF was slightly better than a stock airbox with a drop in K&N.
Which one is better,well that should be decided on what your wallet can handle.If I you have choices and can handle the added expense I would say buy the AFE Stage 2,but,the BHAF will do the job also and is one of the most under rated systems for our trucks.Just make sure when you use a BHAF you have a good seal at the neck and you do not drop it onto the factory airbox studs and tear it.If your not going to make a heatshield for the BHAF its best to cover the exposed factory airbox studs with a acorn nut to limit any damage to your aif filter.
