Bad Gas Mileage

Did some minor mat. on the car this weekend. Install some new NGK plugs and a drop in K&N air filter into the stock air box.

Today I noticed my mileage a bit off. Usally at half a tank I get 350 km but noticed it's around 250 km.

I won't for sure until I fill up next time but could it be the fact that the new air filter is less restrictive so I don't have to step on the gas as much?

It's colder this week too idling at start-up and less efficiant in the cold.

Yeah, plugs are gapped at specs from my helm's manual.

Wondering if it was my driving habits for the past couple of days, shall find out by tomorrow.

Ya I think since its been so cold lately, if you compare your mileage to when you tested it when it was definately warmer, there would be a difference.

Am I correct?

yes you are.

Cold air is denser, and the car will automatically pump more fuel to compensate.

I think its how and where you drive, if you drive on the highway a lot, and drive around 100, you will get better millage, I get OK millage, but my driving is almost all city, so its to be expected

With a stock ecu shift below 5000 and you should be over 400km/l
