Description

The Eps BB70-KIT is a big bore throttle body kit engineered by Engineered Parts Solutions and Tuning, LLC, to enhance the performance of compatible Nissan and Infiniti vehicles. This kit increases the throttle plate diameter by 10mm, from the stock 60mm to 70mm, resulting in a 36.1% larger area at the blade. This significant increase in airflow capacity is complemented by a CNC billet aluminum adapter plate and a plug-and-play harness for simplified installation. The design incorporates a very low merge angle between the throttle body bore and the intake manifold inlet, ensuring a smooth transition for optimal airflow. This contributes to improved throttle response and overall driveability characteristics. This product has proven dyno and track gains. The BB70-KIT is compatible with a range of Nissan and Infiniti models, including the 350Z (2003-2006 and 2007-2008), 370Z (2009+), Frontier, G35 (2007+), G37, Maxima, NV1500, NV2500, Pathfinder, and Xterra.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
