#### **Cons:**1. **Higher Cost** OEM parts are typically more expensive than aftermarket alternatives. The Suzuki 33410-24310/09412 coil may cost significantly more than a generic ignition coil, depending on availability and supplier.
2. **Limited Availability** Suzuki parts for older models like the 1984 1987 Quadrunner can be harder to find, especially if the supplier doesn t stock them regularly. This may require ordering from specialty dealers or online marketplaces, which could delay replacement.
3. **Potential for Counterfeit Parts** Buying from untrusted sources (e.g., eBay without verification or unknown sellers) risks receiving a counterfeit or refurbished part that may not perform as expected. Always verify the seller s reputation.
4. **No Performance Upgrades** Unlike aftermarket coils designed for higher performance (e.g., increased spark energy), this OEM part does not offer any tuning or power benefits. If you re modifying the engine, a specialized coil may be more appropriate.
5. **Age-Related Wear** Even if the coil is new, the rest of the ignition system (e.g., spark plugs, wires, distributor) may be worn out. Replacing just the coil without addressing other components could lead to recurring issues.
6. **Mixed Reviews on Longevity** Some owners report that OEM coils for older Suzuki models (especially those from the late '80s) may not last as long as expected under heavy use (e.g., frequent off-roading or high-mileage vehicles). Aftermarket brands like NGK or Denso sometimes offer better longevity.
7. **Environmental Factors** If the Quadrunner is used in harsh conditions (e.g., extreme heat, cold, or moisture), the coil may degrade faster than average, requiring more frequent replacements.
