Check Valve Option
 

Has anyone ever used anything besides the Mazda OEM check valve in their sequential set up?

DaleClark has a pretty good option. Check his website for the VITON check-valves.

If you want check valves that will probably outlast your car:

I've sold tons of my Viton check valves, and they work great. So far I've yet to hear of a single complaint or failure. Damian's setup referenced above is nice, but they're pretty large and bulky, and probably cost a bit more than mine :).

I also recently updated my valves with larger nipples so they fit SUPER tight - no need for a zip tie or anything.
