The John Deere part number for the JS40 spark plug is M78543 (JD Model JS40 maintenance sheet). I found 4 replacement plugs for the M78543 spark plug from a cross-reference website: Brisk 1326, Brisk DR17YC, Champion 71, and Champion RC12YC. It is important to measure the length of the threads on the original spark plug and compare it to the new or replacement plug. If the threads are too long you run the risk of the piston impacting the bottom of the spark plug; ruining your engine. I've used the Champion RC12YC on my JD E100 riding mower that has a B&S engine with the B&S 491055S spark plug. The Champion RC12YC is one of the replacement spark plugs for the 491055S. **Q: Are these spark plugs b&s plugs or off brand plugs? thank you be safe out there** A: Hi they are briggs and Stratton brand. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good quality, good price, perfect size *by F***O on May 12, 2026* Works pretty good on my push mower, I changed the last spark plugs Briggs and Stratton they long last for around 3 years, I'm pretty sure this one's gonna reach many years... ### ⭐⭐⭐⭐⭐ g *by S***L on May 10, 2026* Received on time, installed worked great ### ⭐⭐⭐⭐⭐ Good plugs *by B***. on May 8, 2026* They came very quick , and fit Dylan mower fine . ## Frequently Bought Together - Briggs & Stratton 491055S - 2 Pack - Briggs & Stratton 696854 Oil Filter Replacement for Models 79589, 92134GS, 92134 and 695396 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ro/products/13521976-briggs-and-stratton-491055s-2-pack](https://www.desertcart.ro/products/13521976-briggs-and-stratton-491055s-2-pack) --- *Product available on Desertcart Romania* *Store origin: RO* *Last updated: 2026-05-22*
