Im plannin on doin a custom cold air just wondering what size of piping i should use. 3 inch or 2.5 ?

how should I go by extending the maf wires.

does anyone have a good write up on thier custom intake.

i have an 95 240sx

thanks in advanced

go with 3 near the cone and maf until right b4 the throttle body, go to 2.5"

thats how the injen intake is i believe. as far as extending the wires, you have two options. add wire and splice or add wire and splice. take a look 2 the project closely and try and figure it out on ur own, youll see it is very self explanitory.

I used a cheap ebay intake as the cross pipe. Seriously, I think it was like 30 bux. It would have cost more to have one bent. The I used a 3" elbow for the extension. The tubing on the cross pipe is smaller but not by much. I don't think it's 2.5"....more like 2.75 or something like that. At the end of the elbow is a giant (4x9 I think?) K&N filter that I ordered locally.

Of course if you're talking about moving wires I assume you're making a shortie, but anyway, this is how I did mine.

rep i like that set up i might do something similar to that one.
is there any noticable power gain?

thanks guys

goddamn that intake filter is low... don't you worry about sucking up water?

If your gonna make it custom, go thru were the battery sits, and relocate the battery to the trunk. The shorter intake piping will produce more power.

Id like to do something like that......I have daytime running lights there but is it OK in the rain?

I have an injen intake that sits exactly like that picture, and I've run it tons of times in the rain. I still have my fender liners in though, so that protects it a lot.

I was, and I'm mindfull of it in the wet, but it really hasn't been an issue. I live in Ga. and it get's pretty wet around here. Also, the filter is 9" tall so it's have to get pretty deep before it'd start sucking water. The top of the filter is right underneath where the OE air box was.

...and chimp is right. A shortie intake would be better all around. I doubt the power difference would be noticeable, but you'd probably notice the quicker throttle response for sure.
