Product Details

The Trans Dapt Performance 2457 is a TBI (Throttle Body Injection) riser plate designed to enhance engine performance on GM vehicles. This 1/4-inch aluminum spacer raises the throttle body housing to allow increased airflow past the injectors, resulting in noticeable power gains and improved throttle response.

Key Features:

  • Constructed from durable aluminum with a black finish
  • 1/4-inch (0.25 in.) thickness provides optimal airflow improvement
  • Allows up to 15 percent more airflow by the injectors for increased horsepower
  • Easy bolt-on installation with included gaskets and mounting hardware
  • CARB E.O. certified (D-578-1) for 50-state legal use
  • Improved throttle response and fuel efficiency
  • Backed by manufacturer's warranty

This TBI riser plate is engineered for direct-fit applications on Chevrolet and GMC pickups and SUVs equipped with throttle body injection systems. Trans Dapt recommends using part number 2458 fuel line extensions for proper installation. The spacer increases intake manifold plenum volume, conditioning airflow to reduce turbulence and optimize the air/fuel mixture for better combustion efficiency.

Great price on a great product! The Thule Raceway 9002 3-bike trunk-mounted rack is what I purchased. Shipping was fairly quick and the product was new, in original packaging and was a great deal compared with other sites for the same product! Would order again!

Took a long time to ship. But was a great deal for the price of the product will order again.

Best price around and good service.

Was linked here by Amazon. I found the absolute best price on the item I was looking for, I had a confirmation as soon as I ordered it, and shipping as prompt. I would definitely recommend these guys and will be shopping here myself in the future.

smooth transaction. good seller.

"Excellent price and great customer service. Order was shipped promptly!! Would do business with them again. "

shopping was awesome and easy , items showed in stk, but delivery was over 9 days

Great prices, reasonable shipping costs. Shipped within 3 days of order. Didn't receive discount for valid coupon code (25OffShipping). No response to 2 emails. No indication of expected delivery date. Lots of unknowns but you can't beat the pricing.

Item arrived promptly (4 days after order), price was good and item was as described.
