Affiliate Disclosure
Keeping it straight: 3 Series Guy uses affiliate links, and we want you to know exactly how that works.
Last updated: May 2026
As an Amazon Associate, we earn from qualifying purchases. If you buy through a link on this site, we may receive a small commission — at no extra cost to you.
What that means
Some of the parts, tools and products we recommend include links to Amazon and other retailers. If you click one and make a purchase, we may earn a small commission. The price you pay is exactly the same — the commission comes from the retailer, not from you.
How we pick what to recommend
Recommendations are based on what we'd actually use on our own 3 Series. We're not paid to feature any specific product, and a commission never changes what we suggest or where it lands in a guide. If something isn't worth your money, we won't point you to it.
No prices on product links
Prices change constantly, so we deliberately don't quote them on product links — always check the current price and details on the retailer's page before you buy, and confirm the part fits your exact car and engine.
Editorial independence
Our problem breakdowns, reliability notes and DIY guides are written to be genuinely useful first. Affiliate links help cover the cost of running the site so we can keep the guides free — that's the whole arrangement.
