Thumbs up DIY "warm" air intake installed

Hi peeps,

I bought 90% of the parts to put this intake together from another Legacy guy here on i-club and I went and installed it all today. It is a Weapon R carbon tube mated to a PDM inline air filter that is run into the fender well. It would be a cold air intake, except I didn't have time to take the snorkus out so it's still pulling air from inside the engine compartment.

I'd been wanting to do this EXACT setup for a while, so when he offered to sell all the parts for $150 I pounced on it. I used to have a K&N panel filter. (anyone wanny buy the K&N??).

Anyway. I am SO happy with it. I took it on a winding road (Muholland Dr. in LA) and had tons of fun. The car is markedly faster and pulls better through the entire rev range. . Not only that, but it sounds really cool. At normal city speeds there is basically no difference in noise, but when you hit the throttle, it does this nice throaty growl kinda like my bosses BMW. It finally sounds like a psudo-performance car should.

By the way, I've never installed anything in my engine without help, so any novice could do this. I think it's well worth it.

so here's a pic:

Default You took out your torque box...

Do you notice any loss of low end power. Also, how do you have the PDM in-line/MAF sensor mounted? How old is the K&N panel filter (I presume it's for the stock airbox) and much do you want for it?

BTW - feels pretty good to do your own work doesn't it? Before you know it you'll be wanting to pull the engine and put in some Cobb "spicy" cams and add your own LSD front and rear...

To answer your questions.

a. I feel no loss in low end power. I was very sensitive to this especially, and was plesantly surprised when there wasn't any loss. The COBB design has no low-end loss either, and this is basically a rip-off of that design.

b. MAF is mounted with a MAF adapter plate and clamps like all other connections you see. It might seem complicated, but it is very simple. I figured out how to assemble it all without directions.

c. The K&N filter is 5 months old. I'd take $25 shipped for it.

Also, it is fun to do your own work, but is is scary too when you turn the key in the ignition and wait to see if the engine is going to explode. . Luckily this isn't rocket science.

cheerio!

I pulled the snorkus out of my BD just to see if there would be any change in the performance range. Once I got it out, and took out the snorkus connector ring at the filter box, I foamed around the opening between the box and the fender (3/16" or so of space there) and taped off the hole for the intake side of the snorkus. I'm waiting to get together a big order in at Subaruparts.com so I can order the correct fender plug and clean up that side of the of the engine compartment.

The last thing I want to do is get rid of the filter box to torque box pipe and put a 2 1/2" mandrel bent smooth pipe in its place. The stock pipe has that little tube like appendage sticking out of it and, without the snorkus in place, it sounds like you're blowing across the top top of a Coke bottle. I believe I'm going to stick with the torque box but could consider a change if the data supports it.

Off-idle and into the rpm registers though, and the intake sounds really menacing and growls nicely. It feels like the engine really reaches into itself now and has even more, smooth, top end pull with no dips or drops in the power band. I can't wait to get the top end done so I can try out a complete exhaust system (header, high-flow cat, cat-back high performance muffler). There must be balance in the universe front to rear/top to bottom

BTW - does the K&N come with the cleaning/re-oiling kit?

K&N is only the filter, and it needs to be cleaned, so you'd need to get a cleaning kit.
