i am too cheap to buy one and i am also a engineering student. i also like to make stuff. so does anyone have any pixs?? and have you noticed any gain from it???

i was thinking a cone filter and 3 inch exhaust pipe.

 

I made one out of two 4" spacers from the auto parts store, a cone filter, a little beather, a peice of steel bent to suport it, and a home depot piece of sheat metal as a heat shield. HIgh school budget gotta love it.

here are the pics

The first stage




All done






I got better throttle response, a little more low end power, and it makes a cool little squeak at 2000RPMS

If you have any questions i will be more than happy to help

 

cool thanks that is what i was looking for.......

come on no one else????

cant wait to start mine

 

i have one and its got the 9 in cone filter, ive also made heat shield and done test it does keep colder air coming in when moving but at idle and stopped its scking in hotter air i dont have any pics right now

 

if your using just a 3 inch pipe off the stock flex hose you may want to get more pipe my first pic is w/ a single 4 inch pipe. I ran that for a few days but then i realized i could add another pipe to push the filter out more thus getting colder air. i'd try to get it out as far as you can

 

Hmmm good idea's i might have to do that this weekend......

And do you have to have a peice of metal to hold it up or could you just let it sit there i just dont see anything tha could hurt it if it layed there......

 

where did you get your filter at? i went to auto zone today and was going to get a K&N but they did not have that style....

 

Check out my thread in the XJ Write Ups, section. Titled "Home Brew Cold Air Intak". It was actually my son's design....and he thought it up at 18.

 

I got it at a local auto parts store Murrays to be exact it was in the ricer area not with the other filters

 

and spectre makes it

 

auto zone has them

 

XJ?2010, Do you have any difficulties getting her through inspection with the CCV breather "only" on it? Thought it had to be captured and burnt in the system.

 

well in michigan we dont have inspections and cops could really care less but there are other ways to do it w/o a breather. example these chrome tubes come in many different styles and you can get them with a little nipple on them so you can just plug that hose right onto it just like the stock airbox.
