Why Choose the Boost Lab BL6662X Billet Turbocharger?

Engineering for Maximum Efficiency

The BL6662X features a point-milled billet 66mm compressor wheel and a newly engineered 62mm Inconel turbine wheel, providing exceptional airflow and reduced exhaust restriction. This results in faster spool, improved transient response, and superior top-end power.

Dual Ball Bearing Durability

Built around a dual ball bearing, oil & water-cooled CHRA, the BL6662X offers outstanding reliability and high-boost capability. Water cooling is required for optimal performance and long-term bearing life under extreme conditions.
