"Works exactly as expected. Install was simple and instructions were easy to follow. I would recommend this product to others." —Wayne G from Kansas City, MO bought an aFe Cold Air Intakes for a 2008 Scion xB.
"Once i got it installed it knocked my socks off ! On my stock air box i removed my breather tube thus making a little gain in power and tone. Once the injen was hooked up it sounded amazin and the power ROCKs. Its one of the faster toasters on the road for sure. It made my xB sound close to an infiniti G37 coupe when its under power. If you have 2008 or newer xB you have to get this its WORTH EVERY PENNEY ! ! !" —Matt J. V from Syracuse, NY bought an Injen SP Series Cold Air Intake for a 2008 Scion xB, Manual transmission.
"The K&N Typhoon was fairly easy to install except for the bracket, could have been a better design there. The system sounds fantastic and seems to have really added some life to my XB! Great purchase!" —Greg A from Gilbert, AZ bought a K&N 69 Series Typhoon Intake Systems for a 2008 Scion xB, 2.4L 4-cyl. engine.
"Install was quick and easy. Works great and engine runs at lower RPMs, has improved MPG and can definitely tell the difference when running at high speeds." —Timothy M from Herndon, VA bought an Injen SP Series Cold Air Intake for a 2008 Scion xB.
"system was an ease to install, looks great and sound great too. Very happy with this purchase, which was a Christmas gift." —Ruben G from Apple Valley, CA bought an AEM Cold Air Intake System for a 2008 Scion xB.
"Part took about two weeks to arrive.Install took about 90 minutes.Directions were precise and had step by step pictues.Fit was perfect,except AEM logo is barely visible with pipe installed properly. Only difficult part of job was that filter has to be slipped through wheelwell then installed from above.Immediately after install there was a noticable improvement in torque.Also engine sound is much more "throaty" especially above 3500 rpms. Since I disconnected battery to do job, my mileage computer reset. My avg. mpg is up to 25 and climbing. I averaged 27mpg prior to the install. I'm hoping to get 29 mpg average with the new intake but the car sounds so good it's hard to keep my foot off the pedal.Overall it was an easy,inexpensive mod with a large impact on performance." —Cindy S from Getzville, NY bought an AEM Cold Air Intake System for a 2008 Scion xB.
"The Volant CAI is everything I wanted. Discrete, a little louder then stock, ease of filter cleaning (if needed), and very unlikely for hydro lock. I even seen an improvement of 1 MPG, cooler Intake Air Temperature, and close to 7 HP from my Innovative App. Unlike conventional CAI, this intakes filter remains in the engine bay with an extension located to a cooler area of the car as a ram air intake would do. All accessories were included for installation. The instructions could of been more descriptive, my TRD strut brace did not fit, and you have to use self tapping screws to install the MAF sensor in place." —Robert B from Virginia Beach, VA bought a Volant Cold Air Intakes for a 2008 Scion xB, 2.4L 4-cyl. engine.
