This may be out there already, but I had a hard time finding the part number for the Mazda ast delete filler cap / housing. Here it is for reference, picked it up from Ray:

Cap / housing - N326-15-17YA
O-Ring - N326-15-174

Water neck cap / housing
O-ring

 

Big Bad Ray will be slingin' FD parts when the universe implodes on itself

I've been bugging him to run a Badass Hot Summer Savings Sale for club members, I'll prod him again tomorrow

 

Just curious, how much was that part?

 

Do you have to get an older housing for this? I wanted to do this but I realized my housing is all one piece.

 

Yes, you'll have to get the 2 piece neck. I prefer the metal one with angled nipple.

 

$55 for the cap / housing and $5 for the o-ring.

 

Thank you. Do you use the existing hoses, or are new ones required? Do you have to re-route the hoses?

 

FYI, a new OEM AST is part #N3A1-15-35XB . Got mine in march, it was $100.48 from Ray.

 

The new plastic nipple on the AST delete routes to the overflow, and the hose off the nipple on the two piece housing routes down to the 5/16th nipple on the bottom of the radiator. I prefer having both those nipples removed and welded up for a cleaner appearance, less failure points, and losing a radiator bypass
