Can you still put a throttle body spacer with this same air intake
Price????
this truck have 2 sensors like a f 150 5.4 2001?
Thanks for putting this video together, it helped me through the
installation. One issue, there were only 2 spacers provided per the parts
list to use to re-install the 4 bracket mounts. Does that mean I re-install
only 2 with the provided spacers? Or do all 4 go back in, with 2 being the
lucky ones?
For specifics you should contact K&N customer service at 800-858-3333. They
can answer your questions accurately.
was the computer tuned after installation and then dynoed or was the truck
dynoed without tuning?
