Choosing the Right Spark Plugs for a 2007-2008 Ski-Doo Legend Trail V-800
Keep your V-800 four-stroke running strong with the correct, reliable spark plugs.
- The recommended and most reliable spark plug is the standard NGK DCPR8E.
- For best performance, replace spark plugs annually as part of pre-season maintenance.
- Always verify the spark plug gap is 0.8 mm before installation.
- Avoid long periods of idling to prevent premature spark plug fouling.
Signs of Failing Spark Plugs
When spark plugs wear out or become dirty, they can't create a strong, consistent spark. This can cause several problems with your V-800 engine. Because they are a simple and inexpensive maintenance item, spark plugs should be the first thing you check if you experience these issues.
- Hard Starting: The engine cranks but struggles to fire up, a common problem in cold weather with weak plugs.
- Rough Idle: Your sled may vibrate more than usual or sound uneven when idling.
- Engine Misfire or Hesitation: You might feel a stumble or a lack of response from the engine when you press the throttle.
- Reduced Power and Fuel Economy: An inefficient spark means you're burning more fuel for less power, making the snowmobile feel sluggish.
- Fouled Appearance: If you remove a plug and it's covered in black, sooty carbon or oily residue, it is "fouled" and needs to be replaced.
Pro Tip: Avoid Extended Idling
Snowmobile engines, including the V-800, are not designed to idle for long periods. Excessive idling can cause spark plugs to foul prematurely, even if they are new. It's best to warm up the engine for a few minutes and then ride at a gentle pace to bring it up to full operating temperature.
Choosing the Right Aftermarket Spark Plug
For the 2007-2008 Legend Trail V-800, the choice of spark plug is straightforward. The original equipment manufacturer (OEM) specified an NGK plug that is widely available and trusted. While other brands exist, sticking with the recommended NGK model is a safe bet for performance and reliability.
Tier 1: Recommended Standard Aftermarket (OEM-Equivalent)
NGK DCPR8E: This is the standard, factory-specified spark plug for your V-800 engine. It is a nickel-alloy plug that provides excellent, reliable performance for everyday riding and is very affordable. For the vast majority of owners, this is the best choice for annual preventative maintenance.
Tier 2: Premium Aftermarket Option
NGK DCPR8EIX: This is the iridium version of the standard plug. Iridium is a more durable material that resists wear and can provide a more focused, consistent spark over a longer lifespan. While more expensive, these can be a good choice if you want the best possible ignition performance and potentially longer change intervals. However, given the low cost of standard plugs, most owners stick with the DCPR8E and replace them each season.
A Note on Champion Plugs
While Champion is a well-known brand, NGK is the overwhelmingly recommended and specified plug for modern Ski-Doo engines. In many forums, owners report better reliability and performance by sticking with the OEM-specified NGK plugs. For guaranteed compatibility, choosing the NGK DCPR8E is the recommended path.
| Tier | Brand/Model | Type | Estimated Price |
|---|---|---|---|
| Standard | NGK DCPR8E | Nickel | $3.91 - $7.00 |
| Premium | NGK DCPR8EIX | Iridium | $9.00 - $11.76 |
Frequently Asked Questions (FAQ)
How often should I change the spark plugs?
It is excellent practice to inspect your spark plugs at the start of every season and replace them if they show signs of wear or fouling. Because standard plugs are inexpensive, many owners replace them annually as preventative maintenance to ensure reliability. Always carry a spare set and the tools to change them when you ride.
What is the correct spark plug gap?
The correct spark plug gap for the NGK DCPR8E is 0.8 mm (or 0.032 inches). While most plugs come pre-gapped, it is critical to verify the gap with a feeler gauge before installation to ensure optimal performance.
Is replacing spark plugs a difficult job?
No, this is a very easy DIY task suitable for beginners. It involves removing the side panel for access, carefully pulling the spark plug wire boot off the plug, and using a spark plug socket with a ratchet to unscrew the old plug and install the new one. The entire process for both plugs should take less than 30 minutes.
Are there any recalls on this snowmobile I should know about?
There are no recalls specifically for the spark plugs. However, BRP has issued safety recalls for other issues on some V-800 models from this era. It is highly recommended to contact a BRP dealer with your snowmobile's Vehicle Identification Number (VIN) to check for any outstanding safety recalls.
