Find a part by its number, brand or name: https://northernperformance.ca/parts/search?q=<words>.

A part has one page, https://northernperformance.ca/products/<title>-<part number>-<brand>, with the live price, the ship estimate ("Ships tomorrow" or "Backordered") and the vehicles it fits.

Find the parts for a vehicle or of a kind: https://northernperformance.ca/parts/<heading>/<category>/<subcategory>?year=<year>&make=<make>&model=<model>. https://northernperformance.ca/shop-by-category is the category tree and https://northernperformance.ca/brands is every brand.

Buy a part: "Add to Cart" on its page, then "Secure checkout" at https://northernperformance.ca/cart, which opens the Shopify checkout. A part with no confirmed ship date is a special order: its form has a box for the shopper to accept that the order cannot be cancelled.

Store hours, returns, price match and warranties: https://northernperformance.ca/llms.txt indexes those pages.
