| i drive 70,000 miles a year...i run k&n filters in all my cars....Def better milage and power...as far as protection to the motor?....ive NEVER had an engine failure and some of my cars have 300k on them...They're def better filters | |

Come on folks, making claims that a K&N improved the fuel economy of a car is just silly. Like it or don't, modern fuel injected engines measure the weight of the air entering the induction system and it apportions the EXACT amount of fuel needed to burn properly. Regardless of what you do with your intake filtration, the preset air to fuel ratio does not change, and as such, the only change in fuel economy is in the mind of the driver and no where else.

 I took my 07 LX Civic for my second trip from St.Louis to South Padre Island. It's about 1,250 miles each way. Since it was a July trip the A/C was on 100% of the time and although I hardly went over 85 mph (Texas is big) I was hardly under 70 would say 74 was about average but if I find a group cruisin I'd join in. So did I get 40 mpg, never but at the speeds I was able to maintain and with the 10% ethenol fuel getting 35 to 38 mpg was impressive. I could get 400 miles to a tank but that is one long stretch to drive. One thing that seemed to eat up gas (to me) was the cruise control seemed to really "drop" a gear on the hills unless I anticipated and kept the little engine humming.

Hmmmm interesting point of view. I guess when my Daughters boyfriend changed his regular "stock" air filter the other day, which hadnt been changed in ages, then he told me he was getting about 4 mpg higher. I told him its because his engine actually is breathing easier. Which is exactly what a K&N does. Any engine breathing more freely will get better gas mileage period. Unless you use the newly found extra power by driving faster or accelerating faster from a stop, then you've lost all the gains. Sounds like our unbeliever needs to go talk to a diesel mechanic, or a few mechanics so he can leqarn about air-fuel mixture. When my brother in law took his brand new truck in, and changed his intake (more air) and exhausr (less air restriction), we took a trip from Phoenix to Ca. Improved our normal stock gas mileage from 21 to 24.7 at 80 MPH with a/c on. Yes both the k&n and there are about 2 other brands out there, will improve your mileage, if and only if you dont lead foot it and lose your gains. I gues we could invite a K&n employee or expert to show actual power and gas mileage gains to our forum, and show you the actuall Dyno numbers on the cars and give us all a more technical explanation to back up what im saying. Trust me, they work, and ive driven over 2 million miles in my life, i've seen the evidence.

Replying to: caaz (Aug 07, 2007 4:36 am) In some intake designs, there are the snow prophylactic effects, which folks like K&N assiduously avoid talking about. To make a long story short, those designs where the snow prophylactic designs CAN but do not necessarily inhibit air flow, a new intake or K&N will provide marginal improvement The price is of course increase "crud" being ingested and injected. But if there is no need for the snow prophylatic designs (which folks that use new intakes defacto decide) then simple removal (of the snow prophylatic portion will unblock the lack of flow that was there in the first place. The concept of course is the removal costs NOTHING! |
