What is the HP, Tourqe specs on a 1999 4.6l engine? And how much HP does th K&N filter add?

------------------
99 F150, 4x4, SC, ORP, 3.55, 4.6l, auto

 

The HP is 220hp. Torque is about 290 ft-lbs by the dyno graph on the brochures.

For a K&N, maybe 1hp. If you remove the air intake silencers (in the tube from TB to MAF and after the filter in the fender) you could pick up a few more HP.

 

Hi

Glad this question came up.

My truck 99SC F250LD 4X4 4.6L A.T. 3.73rear
short bed. (looks like F150)

Owners Guide F150/250 Pg.217 Engine Data:
4.6L 150/250 with manual trans. 220@4500rpm

4.6L F250 with A.T. is 235HP@4400rpm

Both listed at 290lb.ft@3259rpm.

Screwy the way Ford listed this. Whats HP with F150 with auto.tranny? same as F250?

Thanks. OT
