Essential Spark Plug Guide for the 2007-2009 Ski-Doo Legend Touring V-800
Keep your V-800 engine starting easy and running strong with the right set of new aftermarket spark plugs.
- The recommended aftermarket spark plug is the NGK DCPR8E, which is the direct equivalent to the original part.
- Always check that the spark plug gap is set to 0.8mm before installation.
- For best performance and reliability, replace spark plugs as part of your pre-season maintenance each year.
- Contact a BRP dealer with your VIN to check for important, non-plug-related safety recalls for your snowmobile.
Signs of a Failing Spark Plug
When spark plugs begin to fail, your snowmobile's engine will let you know. While these symptoms can also point to other fuel or ignition problems, spark plugs are an inexpensive and simple maintenance item, making them the best place to start your diagnosis. Look for these common signs:
- Hard Starting: The engine turns over but struggles to fire up, a problem that is often worse in cold weather.
- Rough Idle: The engine shakes or runs unevenly when idling.
- Engine Misfires: You may feel a hesitation or stumble from the engine during acceleration as a plug fails to ignite the fuel.
- Reduced Power: The snowmobile feels sluggish and doesn't have its usual throttle response.
- Poor Fuel Economy: An inefficient spark forces the engine to burn more fuel than normal.
- Fouled Appearance: If you remove a plug, a black, sooty, or oily coating means it is "fouled" and cannot spark effectively.
Important Vehicle Safety Notice
While no recalls exist for the spark plugs themselves, other critical safety recalls were issued for some Ski-Doo models from this era using the V-800 engine for issues related to the fuel system and drive axle. The BRP recall website does not list safety notices for vehicles older than model year 2010. It is highly recommended that you contact an authorized BRP dealer with your Vehicle Identification Number (VIN) to check for any outstanding safety recalls.
Choosing the Right Aftermarket Spark Plug
For the V-800 engine, selecting the right spark plug is straightforward. While several brands exist, parts catalogs and owner forums consistently recommend one brand for its reliability and OE-level performance.
Tier 1: Standard Replacement (Recommended)
NGK DCPR8E: This is the standard, OEM-equivalent spark plug for your Legend Touring V-800. It is a copper-core plug that provides reliable, consistent performance for all-around use. For the vast majority of riders who perform seasonal maintenance, this affordable plug is the best choice and will perform exactly as the original factory plugs did.
Tier 2: Iridium Upgrade
NGK DCPR8EIX: For riders seeking longer life, an iridium plug is a premium option. The iridium electrode is harder than the standard nickel, allowing it to last longer and provide a more focused spark. While these are a good upgrade, they are more expensive, and many owners find that the standard copper plug is more than adequate, especially since seasonal inspection is recommended regardless of plug type.
Pro Tip: Always Check the Gap
Before installing any new spark plug, always check the electrode gap. The correct gap for the NGK DCPR8E and DCPR8EIX in this application is 0.8 mm. Plugs can be dropped or bumped during shipping, so verifying the gap with a feeler gauge is a critical step for ensuring proper engine performance.
Aftermarket Spark Plug Cost for 2007-2009 Legend Touring V-800

Frequently Asked Questions (FAQ)
How often should I change the spark plugs?
For a snowmobile using standard copper plugs, it is excellent practice to replace them at the beginning of each season or every 100 hours of use. This prevents being stranded by a fouled plug. Always carry a spare set and the tools to change them when you ride.
Is an iridium spark plug worth the extra cost?
It depends on your preference. Iridium plugs last longer and provide a very stable spark. However, given the harsh conditions snowmobile engines operate in, the more affordable standard copper plugs replaced annually are a very effective and cost-efficient maintenance strategy.
Is spark plug replacement difficult on the Legend V-800?
No, this is a very beginner-friendly task. It typically requires removing a side panel for access, pulling off the spark plug wire boot, and using a standard spark plug socket to remove and replace the plugs. The most important rule is to always start threading the new plugs in by hand to avoid cross-threading the aluminum engine head.
What causes spark plugs to foul on a snowmobile?
One of the most common causes of fouled plugs on a snowmobile engine is prolonged idling. Unlike a car, these engines are designed to run at higher RPMs. Letting the sled idle for long periods to warm up can cause unburnt fuel and oil to coat the plug, preventing a good spark.
