Buying advice

When choosing a camshaft plug, prioritize material compatibility with your engine block (steel or aluminum) and ensure the diameter matches your cam bore. Check for included sealant or O-rings for better leak prevention. For high-performance or high-mileage engines, opt for a premium plug like Fel-Pro or Mahle.
