2014-2015 Toyota Tundra 4.6L & 5.7L V8 Trucks Get 50-State Legal K&N Intake Option
- Dec 28, 2015
Toyota took on the first gen Tundra's critics by introducing a larger second generation Toyota Tundra for the 2007 model year. The second generation effectively squashed complaints about the Tundra being small, but the second blow came from Toyota with the introduction of an all-new 5.7L 3UR-FE V8 engine. The dual VVT-i 5.7L V8 engine was rated at a whopping 381 horsepower and 401 lb-ft of torque. In 2010 Toyota replaced the 4.7L I-Force V8, first introduced in the 2000 Toyota Tundra, with a 4.6L 1UR-FE V8 engine originally used in Lexus models in the Middle East. This new smaller engine belongs to the same engine family as the Tundra's 5.7L engine. It shares the 5.7L engine's 94 mm bore, but with a shorter stroke. The 381 horsepower and 401 lb-ft of torque offered by the second generation Toyota Tundra's 5.7L 3UR-FE V8 is probably more than enough power for most situations. However, there are times such as towing, hauling a fully loaded bed, or even off-roading where a boost in horsepower can come in handy. For 2014-2015 Toyota Tundra 5.7L V8 owners in need of more power, or 2014-2015 4.6L V8 owners looking to close the power gap, K&N has stepped in to offer a bolt on performance upgrade that can be installed in less than 90 minutes and with basic hand tools for both V8 engines.
The K&N 57-9036 performance air intake system is a little different from the average K&N cold air intake system. K&N engineers chose to retain the use of the 2014-2015 Toyota Tundra 4.6L or 5.7L V8 stock air filter box when designing this K&N performance air intake system. Retaining the use of the stock air box allowed K&N engineers to increase performance while leaving all the stock emissions control equipment in place. This allowed K&N air intake 57-9036 to earn an exemption order (EO) from the California Air Resources Board (CARB) for the 2014-2015 Toyota Tundra models listed below. Despite appearances, the K&N 50-state street legal air intake system for 2014-2015 Toyota Tundra 4.6L or 5.7L V8 pickups is precision-engineered to provide a guaranteed increase in horsepower, better acceleration, and improved engine sound. When tested on K&N's in-house dyno, this air intake produced an estimated additional 5.8 horsepower at 5,508 rpm and 5.73 pound-feet of torque at 3,796 rpm over the stock system of an otherwise stock 2015 Toyota Tundra 5.7L V8. Similar results can be expected when this street legal air intake is installed on 2014-2015 models with a 4.6L V8 engine. Street legal performance air intake 57-9036 is designed to fit and function properly on the 2014-2015 Toyota Tundra models listed below:
2015 TOYOTA TUNDRA 5.7L V8 F/I - All CARB EO Number: D-269-52 K&N air filters and air intakes for Toyota Tundra models can be found on the Toyota Tundra Air Filters and Toyota Tundra Air Intakes pages.
