How this site earns money
1. Affiliate parts purchases: eligible retailer links can earn a commission when a visitor buys. 2. Premium reports: optional paid build reports. 3. Qualified shop/tuner referrals: only through disclosed agreements. 4. Sponsored products: clearly labeled and kept separate from compatibility/reliability logic.
Affiliate disclosure: When affiliate links are enabled, Subaru Power Planner may earn a commission from qualifying purchases at no additional cost to the customer. Recommendations should remain based on fitment, build requirements and value—not commission size.
