Performer plus air intake

He asked if it was worth it or not, not how :D

Well besides the way he showed, you can also get a MAF cone adapter from an Altima and drill out the holes larger and go that route. Both methods will cost about half as much as the AC kit ;) .

i personally dont think it would be worth 100 bucks. I'm new to pathy's in general, but for what it is you could spend 30 bucks and do the same thing yourself.

 

Anyone had any problems with water and dirt getting on the filter? I would think it would be a problem.

IM STILL WAITING ON IT.

 

lol, AC takes forever to order from, my Calmini stuff is here, and the body lift and headers are here, but no intake. The one thing I knew I could do on my own and its not even here. Belive me, youll be the first to know.

Dont bother unless you're prepared to construct an isolation box to keep the engine heat out. You can kiss your low end torque goodbye if you stick that junk open in the engine bay.

Hey GrimGreg, does that Altima adapter have an off-center intake hole, like ours? I thought I got one recently on ebay but the hole is centered in the square part of the adapter and doesn't quite match up.

Hahaha try sticking a thermometer in the bay and see just how hot that 'fresh air' is..

If you're not drawing air from outside the engine bay or below the motor you are wasting your time and money. Seems evident every automotive engineer in the industry has recognized this fact...

Hehehehe. A remote thermo will do :)

I had my sensor in the ventilation grille for a short time.. the heat coming up from the hood was enough to register a 5-10degreeF increase over ambient while in motion.

hahahaha...Good comment. So much for "cold air intake".

 

Now I understand that this applies to SUVs and other cars not meant for speed, but wouldn't this apply to sports cars (namely ricers) too? I mean, their engine bay gets hot too. So in other words, does this mean that the "cold air intake" kits are crap?

 

Those filters aren't cheap either. I've seen them for $40 at autozone before.

Actually true CAI's typically have the filter assembly housed in the fender or someplace else outside the physical engine bay.

 

The impact of heat is actually greater on ricers. Truck motors typically generate power through raw displacement (3L, 4L, 5L of air etc). Heat only really effects the low-end when the numbers are low to begin with. At 4krpm, a few cubic inches of air doesnt make a whole lot of difference. Remember hot air = less dense = less oxygen = less power. Ricer's on the other hand (typically 4bangers) generate power through efficient and optimal use of the available air. Every little bit counts with these babies, as thin hot gasses sucked into the intake can have a severe impact all the way through the curve.

 

With our pathies the best bet is to use a drop-in style filter replacement using the stock routed tubing (into the fender), or construction of a true cold-air system (have yet to see a commercial version).

Makes sense. I remember someone saying that their truck seemed to run better with a snorkel. Certainly no harm, as long as it is not restrictive...

When you get it go ahead and mount it up so you have a baseline to compare to. Then build a shield. Not too hard just tin or aluminum sheeting riveted into shape, isolating the filter element so it can only draw air through the original hole in the wall. If you've looked at similar style systems for some other vehicles, many have a flap or shield behind the filter that serves the same purpose. It's not as effective as a CAI, but it gets the job done. If you've already spent the cash ($105 is that right? so thats probably $35 for the cone and 70 for the adaptor) might as well make the best of it.

 

If you ever decide you want the real deal, you can easily build your own and reuse that cone filter if it will fit where you want it.

Here's a page that outlines using mandrel bent steel tubing available at many big-name hardware stores (Casa De Pot, Lowes). The page is written up for Hondas but the application is the same.

Unfortunately the intake is one of the least impacting of many bottlenecks in the VG30, so only so much can be gained by working at this end.

Lower to the ground hmm? If you're referring to that URL the filter looks like it's housed in the fender inside the wrap-around part of the bumper. It is isolated from the road by the wheel well liner. This is the same spot Honda used to (they might still dunno) house all the resonator boxes and assoc. tubing with the stock filter box mounted just inside the engine bay.

I agree that in our trucks putting the filter down low wouldnt be a terribly bright idea, but I have seen little ricers who either couldnt or didnt want to put the filter in the fender, so they brought the tubing down to below and beside the motor. Just being away from the heat is all that really matters without taking environment into account. Hell the older Toyota MR2s had the motor at one end and the intake at the other!

I have yet to pull off my fender and see just how much room there is to play with, but if I ever become motivated to come up with a practical cold-air solution I'll be sure to post a writeup. In the meantime I strongly encourage that others experiment on their own.. I have yet to see a commercially produced cold-air intake for our trucks, and there is obviously a market demand present.. someone could stand to make a pretty penny.

I still think that the intake system along with a shield is beter than a snorkle.

 

Yeh Duffman, Give them slackers a call. you aint gettin any younger and neither is your Pathy. Good luck.
