Under partial-throttle transitions, abrupt geometric transitions into the intake manifold create shearing and boundary-layer separation. This fluid instability impedes intake velocity, introducing off-idle hesitation and diminished torque recovery during low-RPM towing or heavy-load acceleration cycles.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eCNC-machined from billet 6061-T6 aluminum, this hardware spacer lengthens the intake runner tract and incorporates an optimized bore profile to smooth incoming airflow. The extended runner geometry acts as a velocity transition zone, reducing pressure drop across the throttle plate and maintaining laminar flow directly into the intake plenum. Surface-treated with a hard anodized finish to resist heat soak, corrosion, and continuous engine bay thermal cycling, this bolt-on unit installs between the throttle body and intake without requiring ECU recalibration.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px;\"\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e2011-2014 Toyota Tundra\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eEngine \/ Chassis\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e1GR-FE Dual VVT-i \/ XK50\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eStock Output\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e270 hp \/ 278 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eN\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2011-2014 Toyota Tundra Base Regular Cab 4.0L V6\u003c\/li\u003e\n  \u003cli\u003e2011-2014 Toyota Tundra Base Double Cab 4.0L V6\u003c\/li\u003e\n  \u003cli\u003e2011-2013 Toyota Tundra SR5 Double Cab 4.0L V6\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Toyota Workhorse Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle severe duty cycles and continuous towing strain, this solid aluminum spacer delivers rugged mechanical reliability without triggering check engine lights or skewing factory mass airflow readings.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50498890399992,"sku":"DS-E0RHYRWZ8","price":83.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/throttle-body-spacer-for-toyota-tundra-2011-2014-4-0l-1.jpg?v=1789275014","url":"https:\/\/performancechiptuning.com\/products\/throttle-body-spacer-for-toyota-tundra-2011-2014-4-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
