RPM Motorsports Torque Tube 3 Month Review
Iíve had the RPM Motorsports Torque Tube on my Wifeís 2014 ADII limited for 3 months now, I thought I would share my opinions on that vs the stock intake and the AFE intake on my 2016 TH.
The 2014 ADII setup is RPM Torque Tube + K&N Panel Filter in the factory airbox & 245/65/17 Falken AT3W tires on TH Wheels & Factory Wheels and Tires
My 2016 TH has the AFE intake & 245/70/17 Falken AT3W Tires & Flowmaster Super 10 Muffler.
After installing the Tube on the 2014 ADII limited I didnít notice any additional noise, but after driving it around for a while (donít normally drive it since itís my Wifeís) I can notice a subtle difference in noise and can appreciate why manufactures put resonators on vehicles. Under wide open throttle you hear a tiny bit more noise but not much. The biggest increase in noise comes when the engine is under load and the RPMís are between 1500-2000. Most noticeable on the highway with the cruise on in 8th gear and going up a slight incline you can really hear an intake growl then.
Fuel economy wise the Tube is a home run. I frequently drive back and forth about 460kms on the highway and my wife had been driving back and forth on the same route. With the TH wheels on she was getting 9.2-10L/100kms. When I switched the Factory Limited Wheels over, The mileage dropped to 7.2L-8.5L/100kms.
Previous mileage with TH Wheels completely stock was 10-11L/100kms. Generally Iím seeing a 1L sometimes greater decrease in fuel consumption. The biggest improvement seems to be when travelling in to a head wind. The vehicle seldom drops from 8th gear when going up slight inclines whereas before it used to always drop down to 7th gear. With gas 1$ a liter here this tube is going to pay for itself in about 2 more months. Compared to my TH, Iím almost considering switching over to this style, mainly because I can get similar fuel economy gains from a relatively sealed airbox and donít have to worry about an open air filter possible getting water in it, I should note Iíve never had an issue with the AFE on my TH its more piece of mind.
On my TH with the AFE intake with my larger tires Iím getting about 9.5-10.5L/100kms on the highway, With the factory wheels and tires I was 8.0-9.5L/100kms . There may be a bit more of a mileage increase on the AFE vs the RPM Torque tube, but maybe only around .5L/100kms.
Overall Iím very impressed with the RPM Motorsports Torque Tube and its well worth the $100 USD its on sale right now. After playing around with different wheel and tire combinations its really apparent how much bigger tires really kill mileage not only on the KLís but other vehicles as well. The factory 18Ē and 225/60/18 combo is great for fuel economy. Tires only weigh 26.8lbs VS the 39lbs o the 245/65/17 AT3Wís, my 245/70/17 weight 40lbs.
