885SPD Posted November 13, 2009 Share Posted November 13, 2009 Here's what I am going to do! I am going to build an adapter to run an XJ air box in my Pathy. It will probably open up many options for different air filters as well. The reason is I am broke and have an XJ airbox with a K&N so I am going to use it. If it turns out well who knows. Tell me what you think, I think it might be a little more efficient. Simon Link to comment Share on other sites More sharing options...
Kingman Posted November 13, 2009 Share Posted November 13, 2009 Where are you going to put the inlet for the cold air? Link to comment Share on other sites More sharing options...
885SPD Posted November 14, 2009 Author Share Posted November 14, 2009 Similar to stock but a larger hole! I want to run a snorkel so trying to keep it kinda stock! Link to comment Share on other sites More sharing options...
SC88Pathy Posted November 14, 2009 Share Posted November 14, 2009 Here's a much much much easier and far cheaper (free) cold air system for 87-89 Pathfinders. Disconnect the air ducting from the inner fender. Twist the ducting around so that its facing towards the gap between the headlight and the grill. TAH DAH! Cold air intake. Just make sure you twist it back to the stock position when it starts raining or when you're traveling somewhere very dusty. Link to comment Share on other sites More sharing options...
180sx Posted November 15, 2009 Share Posted November 15, 2009 Umm...is this really a cold air system? Or are you just changing intakes? I don't really understand this... Link to comment Share on other sites More sharing options...
885SPD Posted November 16, 2009 Author Share Posted November 16, 2009 OK! The stock air cleaner is very restrictive! What I am going to do is fabricate a plenum that adapts the throttle body to run a 3" hose. Then I am going to mount an XJ air box with K&N in it, using the stock, but opened up, air location in the fender! SC88 that's a ram air, cold air means that you pull air from a location other than the engine bay, so the stock location is a cold air system. Just don't do what a friend of mine did and run it into the inside of his XJ, He could not figure out why He felt light headed all the time (just a hint he lives in UTAH and uses his A/C alot!!!!).

89_trailboss Posted November 17, 2009 Share Posted November 17, 2009 sorry, but it wont work; unless you keep the stock air box on the throttle body. the factory airbox has that wierd hump inside the filter. it creates some sort of volocity that the motor needs to run. the motor will not rev past 2500IIRC. I tried numerious styles of airboxs that sat ontop of the TB so I could run my snorkel. nothing worked untill I cut the stock box where the filter sat and built off there. I dont know why, but the throttle body needs that stupid hump/hill to run. the motor just falls flat on its face without it. 4 different styles I tried. dunno.

nunya Posted November 17, 2009 Share Posted November 17, 2009 Why don't you just get the correct K&N filter since it seems all your trying to do is make some setup to run one you have laying around. Nothing against tryign to build a better mousetrap here, but it seems like your just making a tail chaser here, especially if your goeing to use the same air intake spot... Are you actually goeing to run piping outside of the engine bay to make it a true cold air intake? If so where is the inlet goeing to be? Link to comment Share on other sites More sharing options...

The mass airflow sensor needs the turbulence to work properly Link to comment Share on other sites More sharing options...
