You're starting it cold and it's hesitating. You're accelerating and the engine's misfiring. The check engine light might be on or it might not be. Could be the spark plugs. The L15A engine in your Fit's got four spark plugs and if they're original they're way overdue. Honda OEM part 12290-RB1-003 is the spark plug that goes in your Fit. It's the correct plug for the L15A engine. When spark plugs are worn or fouled the engine can't ignite the fuel mixture right. You get rough idle. You get hesitation. You get poor fuel economy. You get hard starts. Replace the spark plugs and most of those problems disappear. If your Fit's been running rough this is probably where to start.\u003c\/p\u003e\n\n\u003ch4\u003eHere's What Spark Plugs Actually Do\u003c\/h4\u003e\n\n\u003cp\u003eThe spark plug sits inside the cylinder and creates a spark that ignites the fuel mixture. That spark happens thousands of times a second when the engine's running. The electrode inside the plug wears down over time. Eventually the gap gets too big. The spark can't jump the gap anymore. No spark means no ignition. The fuel doesn't burn right. You're getting misfires. The cylinder's not producing power. You're losing power and efficiency. The engine runs rough. Replace the plugs with fresh ones and the spark's strong again. Combustion's clean. The engine runs smooth.\u003c\/p\u003e\n\n\u003ch4\u003eIf Your Fit's Running Rough The Plugs Are Probably Shot\u003c\/h4\u003e\n\n\u003cp\u003eIf your Fit's got rough idle or hesitation on acceleration or hard cold starts the spark plugs are usually the culprit. We've seen people ignore a rough-running engine thinking it's something serious. They're worried it's the transmission or the engine itself. Then they finally check the spark plugs and they're black and fouled. The engine's been misfiring for months because the plugs are worn. New plugs fix it immediately. The engine runs smooth. The hesitation's gone. Hard starts go away. We've also seen people drive around with bad plugs thinking they need a tune-up or a new alternator. The plugs are the problem the whole time. Check them first before you start worrying about bigger issues.\u003c\/p\u003e\n\n\u003ch4\u003eFour Plugs In Your Fit - Replace All Of Them\u003c\/h4\u003e\n\n\u003c!--StartFragment--\u003e\u003c!--EndFragment--\u003e\u003cp\u003eThe 07-13 Fit Spark Plugs, 12290-RB1-003, are sold individually. The L15A engine's got four cylinders which means four spark plugs. You need to replace all four when you're doing a plug service. Don't do two and leave the other two. We've seen people replace only the bad plugs they can see are fouled and leave the worn ones in. The worn plugs are still misfiring. The engine's still running rough. They're confused because new plugs didn't fix it. They needed to replace all four. When you're doing the job do it right and replace all of them at the same time. The labor's already there. You're not going back in there in a month because you skipped the other two.\u003c\/p\u003e\n\n\u003ch4\u003eOEM Spark Plug - The Right Heat Range\u003c\/h4\u003e\n\n\u003cp\u003eThis is genuine Honda OEM part 12290-RB1-003. It's the spark plug Honda installs in L15A engines at the factory. The heat range is correct for the L15A. The electrode material is correct. The gap is correct. When you install this the ignition system works exactly the way Honda engineered it. Aftermarket spark plugs are cheaper. Some are fine. Some are the wrong heat range. We've seen cheap plugs that run too hot and they burn out fast. We've seen plugs that run too cold and they foul up with carbon buildup. We've seen aftermarket plugs with electrodes that wear down way faster than OEM plugs. The spark plug controls combustion in your engine. It's not where you use mystery plugs and hope they work. Buy the Honda plug. It's the right spec for your engine. It sparks right. It lasts. You install it and the engine runs clean.\u003c\/p\u003e\n\n\u003ch4\u003eWhat You Get\u003c\/h4\u003e\n\n\u003cul\u003e\n  \u003cli\u003eHonda OEM spark plug - part number 12290-RB1-003\u003c\/li\u003e\n  \u003cli\u003eFits L15A engine (2007-2013 Honda Fit)\u003c\/li\u003e\n  \u003cli\u003eGenuine Honda plug - not aftermarket\u003c\/li\u003e\n  \u003cli\u003eCorrect heat range and electrode material\u003c\/li\u003e\n  \u003cli\u003eFactory-spec gap\u003c\/li\u003e\n  \u003cli\u003eSold Individually\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eFits These Cars\u003c\/h4\u003e\n\n\u003cul\u003e\n  \u003cli\u003e2007-2013 Honda Fit (L15A engine)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e Spark plug for L15A engine in 2007-2013 Honda Fit. Genuine Honda OEM part 12290-RB1-003. Replace all four plugs at same time for complete spark plug service (four plugs per engine).

Replace every 30,000 miles or per Honda maintenance schedule. Install with correct gap setting per factory spec. Do not install aftermarket plugs with wrong heat range (risk of fouling or burning out). One plug per order - order four plugs for complete service.\u003c\/p\u003e\n\u003c\/li\u003e\n\n \n\u003cli id=\"VehicleFitment\"\u003e\n 2007-2013 Honda Fit \n\u003c\/li\u003e\n\n\n\n\n\n\n \n\u003cli id=\"Included\"\u003e\n(1) Spark Plug\n\u003c\/li\u003e\n\n\n\n\n\n\n\n\n\n\n\n\n\u003c\/ul\u003e\n","brand":"Honda","offers":[{"title":"Default Title","offer_id":45655283269666,"sku":"OHA-12290-RB1-003","price":29.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2218\/5701\/files\/OHA-12290-RB1-003_rty8.jpg?v=1780085996","url":"https:\/\/www.hybrid-racing.com\/products\/honda-l15a-07-13-fit-spark-plug-12290-rb1-003","provider":"Hybrid Racing","version":"1.0","type":"link"}
