First of all, I want to get a blow off valve for my 06 STi, but I'd like some feedback on that from you guys since I don't know if that's a bad idea or whatever, I just think it would be fun.

Second, I need to know where in Calgary I can get one put in...

Thanks for any comments, or suggestions.

Dont waste your money.. they are pointless on subies, and potentially dangerous.

If you "must" have one, you don't need a shop to do it, its 2 bolts, you can easily do it yourself in 15 minutes.

Not sure where you can get one in Calgary. But the install is super easy, just make sure you buy an adaptor flange.

As far as performance wise some people may disagree with using one. I am assuming the BOV you want to buy vents to atmosphere and makes a Swoosh sound. Do a search in the forum, you will find lots of opinions.

Yea, not to open the debate again, but there two views, each with their evidences. One saying that bovs are dangerous and cause the engine to run too rich, leaving unburnt fuel in your uppipe, the other says that this is a load of bullocks and that even 100% bypass is fine.

I used to be of the opinion that bovs are problematic, but after lots of experience, Im getting more and more convinced that vent-to-atmosphere bovs are not a problem, and even if they are, the problems are so minimal that they are negligble.

Most people get sick of bovs after a year or two, but they are tons of fun for the first while. Also, getting an aftermarket bov is a very good idea because the stock piece tends to leak a little sometimes.

So, in my humble opinion, get a bov cuz they are really fun and Im sure you will smile every time you release the gas for the first 2000 times.

Also, I strongly suggest the HKS SSQV because you can buy different inserts (about $30 ea) and change the sound every once in a while. You will get bored of one sound, so this bov, aside from being an excellent one, it is also customizable (but not adjustable in terms of % of venting).

If you want a bov that is adjustable in terms of venting, go with the WORX one. WORX is one of my favorite subaru aftermarket brands and their bov is exceptional.

Just my 2cents.


OH...and install is not "super" easy. An aftermarket bov is usually fairly bigger than the stock one, and will be a tighter fit than the stock as well. It is quite easy to install, BUT sometimes it will require a bit of elbow grease. For example, the WORX bov is adjustable, so you have to hook up the hose to plumb back the air. That hose is under the intercooler and is a PAIN to hook up from underneath if doing it for the first time (it gets easier after). Also, the WORX bov just BARELY fits over the manifold (I had to take off a bunch of piping to get it to sit properly), and you will be jumping up and down trying to press it down low enough to get the second screw in.

So installing is easy enough for you to do it yourself and see what happens...BUT expect to get pretty pissed off at how tight everything is under the STi hood.

Have fun.

If you're going to do a BOV the worx tuning is a great way to go. It 100% recirs the air at light throttle (1st stage piston) and then is adjustable from full atm to full recirc at heavier throttle (2nd stage piston). That way you can get some noise and still avoid the rich shift problems. It also just so happens that i have a brand new one for sale becuase it won't work with my new setup.

Hey man,
So they say blow off valves are bad for your car. I just put a Cobb short ram intake and what a difference it's almost like having an after market blow off valve. The stock one is so loud now it's crazy. Just a a thought, since there is a debate on blow off valves.

I appreciate all the help, guys...

As far as the short ram air kit... I'm assuming that's K&N... where can I pick up the stuff for that?

There are a bunch = Cobb, Perrin, Turboxs to name a few.

Go to the vendors section on this site, and take your pick, everyone sells'em

Intakes are just as bad as a BOV on a untuned vehicle. Check out Cobb's testing of the SPT intake on a Legacy GT and see their results.

That test is true for the Legacy, but doesn't fully apply to the 2.0L and STi.

For an STi the 65mm APS is your best bet if you can't tune for it.

Because the STi is sooo different than the LGT? Intakes have their place (for use with FMIC's mostly) but are pointless on a stock Subaru. Even assuming the test was skewed and the intake actually performs completely opposite than their test and gains 5HP...is it really worth it when you can gain way more with a reflash (without an intake)? Unless you just think they look cool. I just think there are way better ways to spend your first mod money than an intake and/or BOV but it's his car and he can do what he wants.

MMMMmmmm popcorn.

Here is the deal, I just spent $63,000 on this car, and I'm kinda strapped for cash now... I make good money but it's going towards a house and gas and bills... I don't have that much extra to put into mods on a car that I find to be fast enough already, I'm just more interested in making it sound a little better and maybe run a little quicker. I'm not going to upgrade something major, so if that's what I have to do in order to get the sound or whatever that I want, I'll just leave it as is.

well if you spend so much on your car, you shouldn't spend 150 bucks and wreck it. Do some research, save your $$$ on something use-full

$50,150 sticker + GST + Protection Package + Tint + Boost Guage + Financing = $63,000...




And I know I don't wanna wreck my car, that's why I made the thread, to find out if it would. Now that I know, I'm not a moron, and I'll find a better way to make something work.

Often a drop in filter (Perrin or similar) will allow you to hear the stock blow off better. Nor sure about the STi though.

But cmon guys, the stock BOV, even when you remove the "snorkus", is still very quiet (a little "choo" can be heard) and sounds crap. I don't like it at all.

My $0.02 is that you go for it. I have never heard of one real case of someone damaging their car from having a BOV. All the negative press BOVs get are from the "theory" behind what a BOV does, but I have never seen a single real case of any problems.

Have fun and go for it. You will get tired of the sound way before the BOV could do any "damage", that is if it does any at all in the first place.

Or better yet, get your car tuned to work with a BOV. That solves all the possible problems. : )

I agree that a BOV probably isn't going to destroy the car but it can hurt the driveability if you go 100 atmospheric. That is why I recomended a valve that allows the recir % to be adjusted if you have any issues.

There are just better ways to spend the money if you're at all interested in performance.

BOV + CAI + Spinners FTW!

Kidding.. put a cat-back on it, sounds awesome, won't hurt your car or performance.

I think a lot of the problems with the LGT intake were due to the actual shape of the intake. The LGT requires an intake with 2 bends in it while the STi allows for a relatively straight intake design.

I agree that the stock airbox is best, until you need to make the change for an FMIC.

I also agree the price isn't worth the 5 hp.

If the goal is to get a blow off valve sound without harming your STi then click here .

Turbosmart Dual Port is also adjustable, it recircs at light boost and vents at high boost. I have them in stock.
