Tial QR Bov for Evo X

My Tial QR bov came neatly packaged and included the STM flange adapter I've ordered. The package however did not show the correct psi spring or flange weld label, but upon opening it and the bov everything was correct. I drive a 2010 Evo X GSR with full bolts on and other little things like mbc, upgraded forge wga, map manifold and crankcase breather. On Cobb AP Stage 2 map with ETS intake calibration also running ETS test pipe. I gotta say the Tial QR bov I installed with the 6 psi spring pulls harder than the NGR Type S bov I had before. Also it is recirculated to keep the maf happy and don't expect it to be too loud especially being recirculated. All and all this was a very good upgrade and what all the big boys uses lol.

Thanks for shopping with us, Rortana! If you ever have any questions about a product when you receive it, feel free to shoot us an email or give us a call in the shop : ) We appreciate your business.

Perfect but be careful

So this is a great product and works perfectly but I went off my boost gauge for the spring pressure. This reducer significantly changes the amount of vacuum against the BOV and it was fluttering badly on the 20inHg spring. I changed the spring out to a 16 inHg and it worked great.
Then I got new piping and the regular TiAL flange is HUGE comparatively so my BOV was half open at idle. Ended up changing my spring back and now it works great again. Fortunately the springs are affordable/ easy to change and the TiAL products are great.

Thanks for the great review, Andrew! Enjoy.
