Very very nice sound! High quality and powerful Boxer Sound.
Fyi if you're not on speed density tuning with an atmospheric bov it can throw off at ratios since the maf is calculating for it. May get pops but less power eventually.
damn i wouldnt have commented that had i seen you already did lmao
@@stoneyoutdoors8819 lol no one gives a shit....just wants the loud noises lol
You need a tune for tire pressure adjustments bro..
You need a tune with that.
You need a tune now
I miss my 04 STi. Had a HKS BOV too. You need to replace your stock horns with some Hellas next.
Ya i got this on my list ready to make some video. What should i do next ?
Should block off that recirculation line…
Whats to blow off valve called?
Its called Bypass Valve
I put it on my 19' STI, It's a HKS Blow off valve. The one I put on my car is a HKS Super SQV4 Blow off Valve. There's other kinds of blow off valves but the sound the HKS makes is always satisfying to hear while driving around town.
Whats the filter for?
For fine dust or dirt stopping going into the BOV.
@@jfGarage4k oh ok makes sense
@@jfGarage4k The air going into the BOV is already filtered because it's the air from your engine air filter, compressed by the turbo going into your intake manifold. I don't think you will get carbon deposit or gasoline from your intake manifold inside your BOV.
Can you see deposits on the BOV filter ? I'm interested.
Do i need to tune the engine for this my friend i need more information. I have 2011 sti and i want more sound from turbo but for bow i don't want to tune the engine its on plan but not for now 😀
Dont need to tune, its fine to cruse around drive around But if you dont get it to tune the Air fuel ratio gonna run rich and loss boost pressure on every shift (run slow)
@@jfGarage4k i dont want to run slow so first tune engine then this
That investment is about to ruin your day without a speed density tune.
The only negative thing it has is it makes your can run rich. In the super long run it COULD be harmful but it's better to run rich than lean.
😂😂😂
Geez, dude almost runs over his daughter. I wonder if he's ever heard of a car COVER??
Ya i heard about it. where do you find & get that?
if your not on speed density tuning pleassseeeee dont listen to this advice
Don't follow this guy! Wow! No gasket, just install it anyway.
The engine fine No Boost leak its not gonna hurt. It was a Sunday afternoon the dealer close, i pick up a gasket the following day.
