Hey there, can someone help me out here? I've been trying for more than 2 weeks to get this part from Mazda and each time this guy from the dealer sends me stupid wrong parts like a 3 way solenoid valve when I asked for a check valve for the boost sensor.

Can anyone tell me if theres a number for the hose and the check valve that goes from the Boost sensor on the firewall to the TB?

Or do I have to purchase a new boost sensor even if mine works number one?

 

It's not a check valve it's a filter S5A1-18-744

 

You could also buy the Mazda parts for the MAP hoses, but it makes little sense. Just some silicone or standard rubber will be fine.

Thanks, I thought I saw a filter there on a diagram somehwere but a friend of mine told me it was a check valve. Thanks alot, you 2s.

 

I recommend ordering your OEM parts from Ray Crowe at Malloy Mazda. He owns an FD himself (with nitrous no less!) and knows the car inside and out, you don't need part numbers. He also gives club discounts and free shipping. His # is 888 533 3400
