It delivers reliable ignition, reduces misfires, and ensures smoother idling, making it the trusted choice for professional-grade marine performance. ## Description The NGK BPR6EFS standard plugs come pre-gapped as specified by your engine manufacturer. It is always recommended to check the gap before installation. Use only the spark plug listed in your engine owner’s manual. Using the wrong plug can reducing optimum performance, reduce fuel economy or cause damage to your engine. Spark plugs are easy to change with common spark plug sockets. The NGK pure alumina silicate ceramic insulator provides superior strength, reduces breakage and better heat transfer. The Ribbed Suppressor Seal extends resistance and prevents spark “flash over” and misfire plus the triple seal helps prevent leakage. Review: Bought these to replace the ACDelco MR43LTS for my 1996 boat with a 4.3 engine. I installed the AC plugs and started having problems with dieseling after pulling a skier or a tube. I’m not saying these completely eliminated the problem but it certainly improved it. I think the AC plugs run a little hotter. These just work better. Review: QuickSilver is well known for their quality marine components so it is no surprise that after installing 4 of these new spark plugs into my Mercruiser 3.0L the engine seems to be running much smoother and is way better at idle than it was last season. Quality product with quick delivery. ## Features - NGK BPR6EFS Standard plugs are pre-gapped to your engine manufacturer’s specifications - NGK Trivalent metal plating also provides superior anti-corrosion in the marine environment and anti-seizing for easier removal - Check your engine owner’s manual for the correct spark plug and use only the plug as recommended by your engine’s original equipment manufacturer - Replace all the engine plugs at the same time ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00N6DEEGY | | Best Sellers Rank | #158,962 in Automotive ( See Top 100 in Automotive ) #1,110 in Automotive Performance Spark Plugs | | Brand | Quicksilver | | Customer Reviews | 4.8 4.8 out of 5 stars (144) | | Date First Available | 21 March 2015 | | Item Weight | 23 g | | Item model number | 33-816336Q | | Manufacturer | Quicksilver | | Manufacturer Part Number | 33-816336Q | | Model | 816336Q NGK BPR6EFS Standard Spark Plug, 1-Pack | | OEM Part Number | 816336Q | | Position | Front, Rear | | Product Dimensions | 30.48 x 10.16 x 25.4 cm; 23 g | ## Product Details - **Brand:** Quicksilver - **Core material:** Nickel - **Global Trade Identification Number:** 00087295176184 - **Top material type:** Metal - **Vehicle service type:** Motorcycle ## Images ![Quicksilver 816336Q NGK BPR6EFS Standard Spark Plug, 1-Pack - Image 1](https://m.media-amazon.com/images/I/81nBtA1ngjL.jpg) ![Quicksilver 816336Q NGK BPR6EFS Standard Spark Plug, 1-Pack - Image 2](https://m.media-amazon.com/images/I/714wG73ehxL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by C***S on 15 July 2025* Bought these to replace the ACDelco MR43LTS for my 1996 boat with a 4.3 engine.
