Mazda Miata 1.8L BP Custom Header Build Kit

This header build kit has everything you need to bring that Mita 1.8L custom header together. Designed to fit the line of 1.8L Mazda Miata BP cylinder head found in a variety of Mazda and Ford cars and SUV's. Great for building that set of headers for your Miata powered truck or car.

Included is:

• Flanges: 1 American made precision laser cut 3/8� thick header flange to fit the Mazda 1.8L BP cylinder head

• Flange Stubs: Included are (4) preformed flange stubs to help speed up the fabrication process. These stubs are formed to the exact flange port shape, and come in 1 5/8" or 1 3/4" primary tube size.

• Mandrel Bends: We supply (6) 180 degree J bends. Our J bends come with a 6� & a 12� leg. For most header builds, this extra leg length mean you won�t need to buy any straight tubing.

• 4 Into 1 Collector: From there we supply one of our weld-on formed collectors, or offer an upgrade to a super high flow 4 into 1 slip on merge collector with 2 sets of collector tabs.

• We offer these header kits with 3 different collector options:

• Weld-On 4-1 Formed Collector (Collector star included)

• 4-1 Slip on merge collectors with a straight exit (Collector tabs included)

• 4-1 Slip on merge collectors with a transitional exit (Collector tabs included)

• Purge Caps: This simple, but effective method for back purging caps works great. Each kit includes 4 primary caps and one collector cap.

• O2 bungs: Each header builder kit includes 1 weld on O2 bung. Precision machined in the U.S. from 304 stainless billet, these bungs weld beautifully, not like a cast bung

• Tig Filler Rod: Includes � lbs. package of filler rod
