Experience the best in performance and style with the TooHighPsi Billet Aluminum LT4-TVS1740 Lid!

With over 70 years of combined experience in designing, building, and testing OEM and aftermarket Eaton based superchargers, THP Engineering's billet TVS1740 lid optimizes airflow to reduce turbulence and maintain consistent airflow through the intercooler bricks.

Made from 6061-T6, our TVS1740 billet lids are designed to enhance the look and sound of your vehicle. Engineered for perfect fitment under the hoods of Chevrolet Z06, CTSV, and ZL1 models when using our THP port injection plates. These lids provide a 20% increase in volume over the stock GEN1 LT4 lid and a 15% increase compared to the stock GEN2 LT4 lid. This sleek design eliminates excess ribbing and amplifies the desirable supercharger whine.

New lids come standard with mounting hardware and a pair of anodized badges in black, red, blue or bronze, displaying your choice of engraved logo. For custom engraving or UV printing of a logo/name in a font of your choice, provide us with a clean high-quality image, preferably in .PDF, .DXF, or Adobe .AI formats and select "Custom Badge".

Standard Badges include 'TooHighPsi', 'Supercharged', 'LT4 Supercharged', 'ZL1 Supercharged', 'Z06 Supercharged', or V-Series logo.

Proudly made in the USA!
