Estimated 12.5 Extra Horsepower for Select Lexus IS250, IS350, GS350 and RC350 Models

69-8704TP retains the stock GS 350 air box to maintain factory connections and the visual continuity that Lexus is known for

Lexus was first introduced in 1989 as the luxury oriented division of the Toyota Motor Corporation. Lexus models, such as the 2013 and 2014 GS 350, benefit from Toyota engineering, and build quality but are very different from Toyota vehicles on the road. The 2013 and 2014 Lexus GS 350 is equipped with a 306 horsepower 3.5-liter V6 engine and transfers that power to the rear wheels. Rear wheel drive, and a performance V6 differentiates the GS350 from anything offered by Toyota and slots the GS in the mid-luxury class with other cars such as the BMW 5-series or Mercedes-Benz E-Class.

Performance Air Intake System 69-8704TP from K&N Filters for select Lexus IS250, IS350, GS350 and RC350 models

With features like rear wheel drive, 306 horsepower, massive brakes, and staggered 19” wheels, the 2013-2014 Lexus GS 350 is more than just luxurious; it is also a performance-sedan. K&N realizes that the typical GS 350 owner is not only interested in touch-screen navigation, but also enjoys the rush of acceleration and the growl emitted by a performance-oriented engine. This is why K&N Filters has released the new air intake system, number 69-8704TP, for the 2015 RC 350, 2013-2015 IS 250, 2014-2015 IS 350 and 2013-2014 Lexus GS 350 with a 3.5L V6 engine. The 69-8704TP Typhoon Air Intake System is precision-engineered to provide a guaranteed increase in horsepower, better acceleration, and improved engine sound for the GS 350.

The 69-8704TP performance air intake system is a little different from the average cold air intake system. K&N engineers chose to retain the use of the 2015 RC 350, 2013-2015 IS 250, 2014-2015 IS 350 or 2013-2014 Lexus GS 350 stock air box when designing the 69-8704TP performance air intake system. Retaining the use of the stock air box allowed K&N engineers to increase performance while keeping inlet air temperatures, and air / fuel ratios within factory specifications. Utilizing the stock air box maintains the use of the factory cold air inlet near the front wheel, allowed K&N engineers to retain all factory air intake connections, as well as leaving all the stock emissions control equipment in place.

Testing revealed that the factory maze of air intake ducting was a significant source of restriction in the stock air inlet system. Included in performance air intake system 69-8704TP is a free-flowing mandrel-bent aluminum intake tube which helps to overcome the restriction found in the stock air ducting, allowing the Lexus GS 350 3.5-liter engine to breathe easier. Restriction isn’t the only trouble with the stock air intake as it also creates turbulence in the incoming air. The mandrel-bent aluminum intake tube used in 69-8704TP has a smooth and consistent internal circumference for reduced airflow turbulence. To complement the under hood appearance of the 2015 RC 350, 2013-2015 IS 250, 2014-2015 IS 350 and 2013-2014 Lexus GS 350, the intake tube is protected with a durable chrome-like finish that will look great for years to come without the need for polishing.

K&N high-flow air filters provide less restriction than typical paper air filters, and because of this K&N air filter, number 33-2452, is able to diminish restriction inherent to using a stock air filter. K&N Air Filter 33-2452 is designed with our famous high-flow cotton gauze filter media to help increase airflow while also providing outstanding engine protection. 33-2452 is washable and reusable and can even go up to 50,000 miles between cleanings, depending on driving conditions.

All of the design features of the 69-8704TP performance air intake system work together to deliver increased horsepower, torque, and improved acceleration. On the dyno, 69-8704TP produced an estimated additional 12.57 horsepower at 5,498 rpm and 13.62 pound-feet of torque at 4,376 rpm over the stock system. Additional horsepower and torque can come in handy when merging onto a highway, or a spirited drive on a winding mountain road. An added benefit of a K&N intake system is the improved engine sound that will complement the already pulse raising exhaust note of the 3.5-liter engine found in the GS 350.

The 69-8704TP performance air intake system is an excellent upgrade for your 2013 and 2014 Lexus GS 350 with a 3.5L V6 engine. With simple to follow instructions and no need to make any other modifications to the vehicle, you’ll be on the road in 90 minutes, or less, with more horsepower under your right foot.
