DIY intake tube

i got an styrene coupling tube measuring 3.5 inch o.d. X 3 inch in length.
the inner coupling ridge was removed and the length shortened by roughly 3mm thru some grinding and cutting to fit and clear everything.

this tube fits perfectly inside the accordian tube and successfully covers all the ripples and stops at the 3 vacuum hoses and clears the front coupling clamp to the intake.

i know there are more expensive aluminum alternatives and prettier ones... but this cost me only $.79 at home depot!

it works just fine and keeps the 3.5 inch to 3 inch transition of the stock intake tube. it simply smoothens out air flow by blocking out the ripples from the stock accordian tube.

don't expect an definite increase in power with this. just expect a more crisp throttle response as the accordian tube's air flow is smoothened out and the tube no longer constricts on high vacuum...

NOW, i just wanted to get some opinion on who thinks this is a rather good cost effective route or... do
you think its really ghetto and would sacrifice transitional dimensions if given an aluminum tube?



p.s. this makes for one light and stealth mod. another reason for my motivation...

^^ darn it nyc! its a nice piece i'm sure... but from all those time i put into modding the stock intake, this is THE last step and effort i'll take.

i DID remove the RB duct for the stock VFAD as there was just too much cleaning with the K&N drop-in to tolerate with. so i just wanted to make up for it in other areas where i can decrease restrictions as much as possible, even if its a minute one.

o btw nycgps, out of curiosity, is ur aftermarket intake tube one size all the way thru...?
the stock box is 3.5 inch and the TB is smaller. hence the reason if i wanted to run the stock box and keep the tube, an insert was my cheapest alternative to keep those dimensions.

K&N's Typhoon pipe is bigger than the throttle body. but I've never measure it myself. its a little bit bigger, not too much.

Im still waiting for CAI to come, but I've seen post about it and its actually smaller than the OE box pipe size. dunno.

i just knew pics are gonna be requested... its a hassle, sorry.

i'll show u at the meet if possible. its just a pvc pipe in place inside of the stock oem intake tube...mated perfectly and blocks off the accordian ripples.

kinda like getting an aftermarket intake anyways where u have to connect 2 tubes together with a hose clamp.

this way is stealth in that its just a tube under ur stock intake tube...

i'll show u at the meet if u like

thanks nyc. so is it smaller?... well that kinda blows. maybe not by alot anyways...
i dun think it matters too much as the velocity stack inside the box don't seem that big anyways... but its been a while since i looked at it.
