This is the Alliant Power AP90008, the high-pressure turbocharger from the two-stage turbo system on the International MaxxForce 13, remanufactured by Alliant Power. The original is a BorgWarner B2XG, which catalogs sell as the high-pressure turbo with actuator. It replaces BorgWarner 12709880008, 12709900008, 12709880075, 12709700075, 12709700191, 12690011001 and 12700011001, Navistar 3005380C1, 3005699C91, 3005699C92, 3005699C93, 3007665C91, 3007665C92, 3007665C93, 5011053R91, 5011054R91 and 5011054R92, and Caterpillar 376-2753. Catalogs list it for the International ProStar.

These engines run two turbos in series, so low boost, slow spool, oil in the charge pipes or a noisy turbo can come from either stage. Check both, and check the actuator, the interstage piping and the charge air cooler before you order. This listing is the high-pressure turbo only. The low-pressure turbo that pairs with it is a BorgWarner B3RS (13879880004), a separate part. A refundable core applies to this remanufactured unit.

Specifications

Fits / Applications

• International MaxxForce 13, high-pressure stage of the two-stage turbo system
• Catalogued for the International ProStar with the MaxxForce 13
• High-pressure turbo only. The B3RS low-pressure turbo is a separate part.
• Match the BorgWarner and Navistar numbers on your turbo tag before ordering

Find out why the old turbo failed before you fit this one. Change the engine oil and filter, check the oil feed and drain lines, prime the turbo with clean oil, and inspect the low-pressure turbo and the charge air cooler for oil and debris. Fit new gaskets and seals.

Frequently Asked Questions

Is the AP90008 the high-pressure or the low-pressure turbo?

It is the high-pressure turbo of the MaxxForce 13 two-stage system, a BorgWarner B2XG. The low-pressure turbo that pairs with it is a BorgWarner B3RS and has a different part number.

What numbers does the AP90008 replace?

My turbo tag says 12709880007. Is the AP90008 the right part?

No. BorgWarner 12709880007 is a B2NG, a different MaxxForce 13 high-pressure turbo with Navistar numbers in the 3004742 and 3007368 series. Call 530-668-0818 with your tag number and we will find the right one.

Is the AP90008 new or remanufactured?

It is remanufactured by Alliant Power. A refundable core applies, so your old turbo comes back to us.
