Enlarged Throttle Bodies


  • Enlarged & Modified Throttle Body - Z20LET / Z20LEH

    Enlarged & modified Throttle Body for Z20LET/LEH engines.

    Vastly improves Airflow and Throttle Response. Fully stripped down and inspected, then vapour blasted to bring it back to an 'as new' condition. The bore of the throttle body is then enlarged from 57mm to 62mm, and the spindle is re-profiled. The unit is finally reassembled with the low profile spindle and enlarged butterfly and then fully tested. Any worn bearings and motor brushes are replaced as a matter of course, so the item is essentially a fully refurbished as new item but opened out to a 62mm bore, 5mm larger than the original spec. Usual gains of 5-10 BHP are to be expected (depending on vehicle spec)*

    Please note: These units are sold on an exchange basis, and a £50.00 surcharge is included in the price. Once you have received your enlarged throttle body, we will require your old one to be sent to us, and your surcharge will be refunded.

    *Although we cannot guarantee specific gains from vehicle to vehicle, we have had feedback from previous customers who have used these on highly tuned engines, some of which gained up to 20 BHP in the midrange following the fitment of one of the units!
