Are these car-care tools really free?

Yes. Every lookup on this page is free to use with no account, no email, and no paywall. We make money through affiliate links when you choose to buy a part, not by charging for the tools.

Do I need to sign up to use them?

No. Pick your car (or paste a VIN for recalls) and you get the answer on the spot. Signing in only matters for community features like saving products to your garage.

How accurate is the fitment data?

We only show a tire size, wiper size, or cabin filter once we've cross-checked it against real sources, and we tell you how confident we are. The final word is always the sticker on your car (the door-jamb placard for tires, the blade stamp for wipers), and we point you there every time.

What other lookups are coming?

We're building out spark plugs, oil weight and capacity, engine air and oil filters, and headlight bulbs next. They land here as each one clears our sourcing bar, so it's worth checking back.
