What does the A/R 1.00 ratio mean for my turbo?

The A/R ratio (Area/Radius) indicates the size of the exhaust housing. A 1.00 A/R generally offers a good balance, providing decent responsiveness at lower engine speeds while still allowing for strong power output at higher RPMs. It's a versatile choice for many performance builds.

What does 'Multiple Fittings' refer to?

This means the housing comes with several connection points for various hoses and lines. This offers greater flexibility when routing your exhaust plumbing, wastegate lines, and other necessary connections for your turbo system.

Can this turbo housing be used on any turbocharger?

This housing is specifically designed for HKS turbochargers that utilize the 4R frame. It's crucial to verify compatibility with your existing or planned turbocharger to ensure proper fitment and performance.
