Im not real knowledgable on the Australian models but if its anything like the usdm models the bov is your problem. Take it off and go back to stock or a recirc one. Forge makes a nice one.

 

Hi
thanks for your reply.
I only put the BOV on yesterday however the popping/backfiring has been going on for about a month.

 

yall gotta stop hatin' on the bov's i have one and i have no problems because of it! and it sounds like i can intimidate other cars because of it. lol.

...fixed it for you.

 

lol or my car came with one and im too cheap to fix it...

 

Needs blinker fluid

 

Your BOV isn't helping the issue OP, what you seem to be hearing is after fires. Your exhaust is igniting your excess of fuel. This defiantly does come from bovs. But you just fed the fire you already had, could you upload some under the hood shots for us so we could maybe better diagnose what's going in. We may be able to see other worn aftermarket stuff that you may think is stock...

Kid, unless someone has real power, I'm always gonna hate on them, especially HKS and TXS... Sorry xoxoxo

 

b4 i bought my car the guy i bought it from douched it out and i had a perrin sri without a tune and a 300 dollar hks bov. does the car really run that much better with the stock bpv? i dont know i never drove a wrx without the bov. is it expensive? tho i have to admit i really love that sound it makes, tommorow i am gonna data log with my ap, hopefully the bov isnt a problem...

 

Night and day my friend. If you still want sound and feel you need it, than get a Cobb xle 50/50 and open the atmospheric vent. It will still recirculate back to where it needs to go but still blow off and give you that sound. They run around $300 as well so buy one then sell your HKS. Or get a stocker for dirt cheap.

Trust me from my experience , it's well worth it
