Compact design for tight spaces

Premium materials & maximum heat resistance

TiAL engineers rely on advanced materials to guarantee durability under the harshest conditions:

• 347SS stainless steel housing & valve – extremely heat resistant

The result: a wastegate that delivers stable operation and is built for long-lasting, reliable performance.
