Have a 2012 Scion tC. My average mpg is 26.8. I would like to know what everyone else is getting. Everything on the car is stock. I was thinking about going with an K&N Air Filter or K&N Air Intake.
Which ever one gives me more mpg. Ive heard that the filter isn't really noticeable. Would appreciate it if someone commented

I have the Injen Cold air kit. I get usually about 26-27 city. If I do all highway, I have seen as high as 33 mpg for a whole tank if I cruise at 70. Probably only an increase of about 1mpg over stock if anything. I also have 19 inch wheels/tires so that would negatively effect mpgs. Wider tread = more friction= worse mpg.

Gotcha. How is injection cai? I want to go with k&n cause that's what i have on my mustang and im impressed. Im not to familiar with imports

this is the one im looking at

Klope1

stock i was getting 27.4 mpg after mods (listed in signature) i'm getting 28.7 mpg

Jaygray757

i was thinking about going with K&n can. but im still doing my research. im trying to get 28 mpg combined. thats my goal if not as close as i can

Klope1

an intake may add an slight improvement in mpg it truly all depends on how you drive and the driving conditions (highway/street). prior to the unichip when i had the intake, cat-back, and headers i was getting 26.5 to 27. after the unichip with 93 oct i started getting 28.7 mpg

Thatguyaknow

I get 24 in the city, but thats just how i drive (=

Jaygray757

Does the unichip really works?

Klope1

it does and greatly improves driving fun! more people are starting to buy them and people that were skeptical about them and decided to buy it are pleased. i suggest going to premium fuel for best results.

MadFunnyBruh

Agreed, it all depends on how you are driving...my mpg is low kinda, but thats because of they way I drive. so yea, my 5 cents.

I'm actually in the low 20s with an Injen CAI, Megan midpipe, Unichip, and Nst pulley. I have a HEAVY foot.

Hiker89

I consistently get 28.1 MPG.

I'm close to getting on average 27 mpg stoxk

I have the 2013 Tc manual. I bought it brand new for a fun commuter that is less painful on my wallet than driving my lifted Jeep @ 3,000+ miles per month. I have 10,000 miles on it now. I obsessively log every tank of fuel since new including the avg MPG, odometer reading, driving style, gas station brand and even the cost of gas! (and kept every fuel reciept) I have no idea what is wrong with me but that another topic.

I have a combined driving of city/highway at 4,500 ft elevation and I commute over a 9,000ft mountain pass 5 days a week. I was *hoping* to get an average of 30 mpg's out of this car. I drive 'spirited' but not aggressive or mild...it does see redline on occasion. Since day 1 the car has averaged 27-28.5 mpg's in stock form depending on the driving style, but I most often see around 27.5mpg's, lowest of 24.2 and highest of 30.8.

At 1,500 miles I installed a Weapon 'r' intake. Nice product, good quality...mileage instantly dove to 25, then I reset the computer. Mileage returned to about 26.8 average. I removed the intake for the 5,000 mile service and reset the computer 'just in case' cause I had an unusual engine rattle (turned out to be a defective cam gear, under warranty...but I didn't want them blaming the intake and voiding the warranty). I have not put the intake back on and do not plan on doing so. (actually I ended up adapting it to my Jeep lol.)

Obviously with my experience the intake did negatively impact my fuel economy slightly. On the other hand while it was on the car I did notice a slight improvement in performance. Huge? no. Noticeable? yes. Also it gave both the engine and exhaust a much healthier aggressive tone that I liked, but at the cost of fuel economy...so back to the drawing board with my stock air box back in. I am actually going to be trying downsizing the rims next as 16" rims will fit our cars...it has been a proven fact the larger the rim, the more negatively it impacts fuel economy (to a minimal degree, but still an impact)...tirerack is having a sale right now; just got some ordered today 16x7.5. Fuel economy aside I wanted a set of 16" rims for snow tires in the winter anyway cause they don't make studded snows for 18" rims in our size...and honestly I think the ride quality is crap with the 18's for a commuter. But I digress; had I done it over again I would not have spent the $200+ on the intake for fuel economy purposes, but thats not to say that ALL intakes will have such results; perhaps others are designed differently and can improve fuel economy.

Also, the computers avg MPG readout on the odometer display lies. I find it to consistantly be 1-1.5 MPG avg OVER what my real average is, so don't believe what that thing is telling you. Manually calculate with the trip odometer to be 100% accurate

Thanks for everyone's input. I just put in a k&n filter for now. I work at ore illy auto parts so my discounts are awesome. I'm interested in the unichip. Where can I get one from klope1

unsungfate

depending on where you live, your mpg will be different than to others.. I live in LA county and because of all the slight inclines, I can't seem to get better than 26-27 combined mpg.. and that's with a crazy light foot! when I'm heavy on the pedal, the car drops to 23-24 combined mpg..! oh well, the motor always pulls strong and it's not that big a deal on my wallet....
also, aside from a modified exhaust, my tc2 is completely stock.. I used to have an aem cai, but it gave me problems with the idle and would shut off.. I still have it and looking to sell it...

Jaygray757

Oh okay. With the k&n air filter im getting 27.1 but at first I was getting like 27.3. It droped im trying to decide ot a cai will help it.i know it depends on the foot..and I dont have a heavyfoot unless I'm in a hurry. I also want to get thr unichip. If anybody has it let me know how you like it
