I'm working on it right now actually, it's consisting of a 4" rubber elbow, a specifically trimmed 4" turndown (trimmed to form a 23.5* angle as this is what fits perfectly), a small extension of 4" tubing, and a nice big cone filter. This will run like the SLP intake except it will be 4" all the way to the filter with smooth bends. I just finished removing my A/c system so that's helping as I can move the radiator forward (no condensor) to make room for the 4" pipe but with some wiggling/adjustment of the radiator and condensor still in, it's a tight fit but does work! Will let you all know how it goes and have pics when its done!
Here's some specifics on the pipe air flow capacities that might be helpful, although our N/A engines only can pull so much I still think a smooth 4" intake would help when other mods are on:
(These numbers are calculated using basic math formulas, [pi * radius * radius * height] is the area of a section of pipe with depth and should show you how much more air the bigger pipe can handle, I also did the calculations in a 3" section of pipe for anyone who wanted to see the numbers for a pipe with actual depth):
Stock Airflow: who knows but it sucks!
Single 3" Pipe:
total area in 3" length of pipe -> 21.195 in
Dual 2.5" Pipes (SLP):
total area in 3" length of pipe -> 29.4375 in
Single 4" Pipe:
total area in 3" length of pipe -> 37.68 in
All other intakes have restrictive crimps near the radiator/abs module section that kill airflow. Also, any metal intake is going to absorb heat so there isnt much to do about this if you dont want plastic or pvc pipes. Therefore I don't see the need to put a 90* angled section to make the pipe go down into the lower fender area like SLP does but you could always do that to this intake if you wanted to, as far as I've seen that cold air benefit seems to be gone when the engine/intake heats up.
