Swap K&N CAI back to stock(ish)

I bought my truck (1996 4x4 3.4L) with a K&N CAI. Is there anything I'd need to swap the intake to a 1998-2003 stock setup besides the airbox (

17700-07060), intake tube (17881-62170), MAF sensor (

Good plan!

That engine bay looks really dirty.

Underhood insulation blanket is rotten. Recommend you just yank it off. The least of your worries at this point is the possibility of your hood paint bubbling.

Your existing K&N filter is so filthy and clogged that it looks like it has collapsed. You already know that.
------------------------

Put the intake idea aside for now and clean up your engine bay first. Seriously, I would be reluctant to even pulling the oil dipstick out with an engine bay that looked like that.

No bueno.
-------------------------

You need a trip to your local coin-op car wash and a roll of quarters. Bring someone with you who knows what they're doing.

Start there. But you have the RIGHT idea.

 

Sounds good, will do. Do you know any good guides to washing an engine bay? I don't have anyone locally who knows what they're doing unfortunately.

EDIT: I can figure it out, just gotta figure out the parts I need to swap my intake back to stock.

 

Why change the MAF if it's working?

Totally agree with getting rid of the "cold air" intake though. They really don't do anything but cause problems.

 

I'm not sure it's not going out, the truck seems to hesitate at medium-high revs and high load. So I'm considering replacing it. Plus the 98-03 MAF sensors are significantly cheaper than the 95-97 MAF sensors.
