N54 BOV's: Tial vs HKS

After many requests about the difference in sound of the TiAL Q and HKS BOV's we decide to upload a short clip of both of them side-by-side. Enjoy!

I know this is an old video, but to anyone that has an N54 (especially the configuration in the 335i), one of the best mods/upgrades you can do that will ACTUALLY help put down more power in the future is the inlet ducting. Those intake tubes pancake down at the firewall and core support between the filters and the turbos. They also soak up a lot of heat with how they're routed and are a lot longer than need be. On my old 335i, I got a drop-in (which is pretty loosely used if you've looked at how/where the inlet pipes are placed) dual short-ram intake setup that put the filters just behind the passenger headlight. After the tune for that intake setup alone I saw an extra 25-30hp. Stack that with a 3.25" straight-piped turbo-back exhaust (with cat delete pipes), intercooler & piping, higher rate fuel system, upgraded turbo charge wheels, stage 1 cams, and a larger set of oil & water coolers, I was pushing up near the 500hp mark. Much more than that and I would have started needing to rebuild the head and upgrading the transmission.

Sure, BOVs are dope, but they don't do much of anything of significance aside from _MAYBE_ preventing a bit of conpressor surge (which is/was a totally overblown consideration.) But those inlet pipes

N54 misfiring at the end, N54 problems 🤣

Went with HKS SSQV myself.. No adjustments necessary, no fooling with springs etc. Set it and forget it...

I had purchased a forged one on my e90 the blow off sound would not activate. I cracked it open and the spring was stuck lol I now have a hks on my e92 and I like it obviously the higher the rpm the higher the blow off sound

Hey friend sorry I’m doing research and going to upgrade my 07 335i lower and top charge pipe with vrsf and debating to get a tial q bov as well.. do you enjoy the bov or find it worthwhile? Tial or hks which is better?

Can you get a BMW 535i charge pipe with the HKS flange? I only see the Tial flange one listed on your website for the 535i.
