Q 1. Which Bosch original-equipment starter motors does the WAI 17813N replace?

A. The WAI 17813N replaces four Bosch OE starter motors: 0 001 110 059, 0 001 115 011, 0 001 115 013, and 0 001 115 118. If you have a Bosch part number from your existing unit, search our cross-referenced catalogue or ask Simon to confirm the match. Every OE cross-reference shown is backed by our Fit Guarantee.

Q 2. Which Porsche models will this starter motor fit?

A. The WAI 17813N covers 15 Porsche applications, including the Porsche 911 (1990–1998). Use the selection widget to match your specific model and engine variant, or search by OEM number to confirm fitment — every application is backed by our Fit Guarantee.

Q 3. What are the key technical specifications of this starter motor?

A. The WAI 17813N is a 12V, 1.7kW PMGR (Permanent Magnet Gear Reduction) starter motor with counter-clockwise rotation and a 10-tooth drive gear. It is cross-referenced under Lester numbers 17281 and 17813, and is supplied brand new.

Q 4. What does PMGR mean, and why does it matter for my Porsche?

A. PMGR stands for Permanent Magnet Gear Reduction. This design uses permanent magnets in place of wound field coils and incorporates a gear reduction stage, producing strong, reliable cranking torque from a compact unit — the same configuration as the Bosch original it replaces.

A. The WAI 17813N is cross-referenced under Lester numbers 17281 and 17813, and replaces Bosch OE references 0 001 110 059, 0 001 115 011, 0 001 115 013, and 0 001 115 118. Enter any of these numbers into our catalogue search, or use the selection widget with your model and engine details to verify fitment.

Q 6. Is this part covered by your Fit Guarantee?

A. Yes. Every vehicle and OE cross-reference shown for this part is checked against manufacturer data and backed by our Fit Guarantee. If it is not right, our Fit Guarantee or hassle-free returns have you covered.
