Understanding Customization and Warranty Implications
Many Si owners consider performance modifications. Your manual provides crucial information regarding:
- Warranty Limitations: It clearly outlines what types of modifications might void your warranty. Always check this before installing aftermarket parts.

Relevance for the “Off-Road” Mindset (Even for an Si)
