Looking at an 04 L, appears to just have an aftermarket intake. Can you tell from the pic of the motor if anything else has been done? Motor looks clean and not like they just prettied it up for the photo. Thanks for any info.
I spy with my little eye....
A C&L Upper intake plenum
BBK Throttle body
Airaid Cold air box
Oil Separator kit
If someone went as far to change the upper intake and throttle body they would usually add a larger balancer pulley too. Can you take a picture of the lower pulley? The one on the blower looks to be stock. Other than that looks very clean! It's tastefully modified but not totally stock. I would look inside the Kick Panel up at the PCM to see if it has a chip. Otherwise it may have been flashed.
Thanks for the info Jim, I have a JDM tune on my 08 F150 Roushcharged out here in CO so I would get another JDM tune if I bought it and figured out what I had on there for sure. I'm currently in Saudi Arabia so I can't take a pic but I'll see if I can ask the person.
Could someone explain the purpose of the plenum? Just increased air flow? Thanks
