In this thread I will share with all you Subaru owners like me who are low on cash how to build a Short Ram Intake for your 98-01 Subaru Impreza. The intake only takes about 30minutes to build and install.

1.Supplies:
  • Flat Head Screw Driver
  • Access to a dryer(such as hair dryer or something to heat rubber without melting it.)
  • Phillips Head Screw Driver
  • Filter Oil/Cleaner
2. Next drive to your local Autozone and purchase 1 3-3.5in 90 Degree Stainless Steel Pipe(can be found under intake piping, not the steel pipes because theyre too small and rigid.) 1 3-3.5in 60degree Stainless Steel Pipe, 1 3-3.5 Cone Air Filter, 1 3-2.5in coupler, and 1 3-3.5in couplers.It should total out to be approx. $60.

3. This is the easy part. Next when you get home, take apart your stock intake leaving the large air box at the intake manifold, but remove the flat rectangular filter in the box. (I use the box because it is where all your vacuum hoses are hooked up and this way you wont need to drill any holes in the new pipes.)

4. Next piece together the 90degree pipe to the 60degree using one of the
3-3.5in couplers. This is where the dryer or hair dryer come in. The couplers have been sitting in the packaging for who knows how long, and they won't easily fit on to the pipes, by heating the coupler it will allow you a few moments to squeeze the pipes together with the coupler.

5. Next, grease the cone filter. FOLLOW THE INSTRUCTIONS ON THE PRODUCT.

6. Now fit the filter onto the 60degree pipe.

7. Next fit the 3in side of the 3-2.5in coupler onto the 90degree pipe. then fit the 2.5 side onto the factory air box pipe. tighten the bolt very tightly that way your positive it wont move.

8. Test the product, make sure all the connections are tight and no air escapes.

You can refer to my cardomain page(www.cardomain.com/ride/3039606/4) to preview how it should look when finished. I used this mod for 5mo. until a friend of mine didn't want his unused Injen Cold Air so I took kindly took it off his hands.

YOUR CHECK ENGINE LIGHT WILL TURN ON, BUT GIVE THE CAR 2-4 DAYS FOR IT TO ASSIMULATE THE MOD. It should turn off on its own.

With this mod you will see increase in hp, gas mileage and your engine will sound more fierce than stock.

Looks good. You should reset your ECU by disconnecting the battery after you are finished. I installed a "hybrid" intake... aka just the tubing to the airbox... and when I first started the car, it idled horribly. I turned it off and started again... same thing. Then I reset the ECU and it worked good. After a few weeks of driving around, it's running 100% good.

This is good but the only problem i find with it is that ram intakes are designed out of one piece tubing for a smoother airflow leaving the stock airbox wil create turbulant air before enterin the manifold. so you might have a cool sound but really probably just hurting the performance

apparently, retaining that box allows you to keep your torque numbers fairly similar to stock instead of losing some.

don't quote me, but i'm pretty sure i read that somewhere.

I had a pipe about a foot long off the tb. check my members journal.
no loss of anything, and an insane wastegate-sounding chirp up top.

it would if instead of removing the filter you left it on like in the ganzflow intake but in this case the air goes in and bounces around the box before entering. I mean im no engineer but i work with ram air and bleed air systems on aircraft everyday and i mean thats just the way i picture the airflowing, when i picture it in my head,

wow, thanks for all the comments everyone. but i've moved onto a two piece cold air intake. for those of you with a maf sensor, what you can do is drill a hole a little smaller than the sensor into the plastic pipe and put the sensor there. but i wasnt aware that the 98-99's had a different set up sorry.

so if i built this SRI, i could just extend it into the fender and then i would have a DIY CAI right? Pros/Cons CAI vs. SRI

yes. you can extend it to a cai but the con with a DIY cai like what your thinking of is there will be waaaaaayyyyy tooo many bends and that will ultimately reduce hp and gas mileage.

CAI;
Pros: doubles gas mileage, louder engine growl, enhances looks of engine bay, much lighter than factory intake, better pick up, creates more room in the engine bay, uses cold air which is healthier for your engine.
Cons: a bit expensive, slight pain to install.

SRI;
Pros: better gas mileage, a little louder engine growl, enhances looks of engine bay,lighter than factory intake, some more pick up,easy install, cheap.
Cons: uses hot air in engine bay which isn't always good air for the engine can reduce power, sharper bends.

although i made the SRI sound better, trust me the CAI is worth your money, especially with the location if you own a 00-01 impreza cuz they dont get too dirty. i dont ever plan on going back to the sri or factory.
