I have a BMW 535i and I want to put a cool air intake and a new exhaust system for added horse power, will this reduce fuel economy?
sure they do. yet all of them do an identical ingredient. All a chilly air intake is, is a steel pipe with a clear out on the tip. do no longer waste your money on okN, AEM or any kind names like that. They value around $220. i bought a chilly air intake for about $30 from OKorder with transport risk-free. they are ordinary to place in, advance your throttle reaction and supply you everywhere from 5-15 horsepower. They replace your production facility intake equipment which takes in air out of your engine compartment that's warm. A CAI takes air under your engine compartment or wheel base that's cooler. Cooler air molecules are tighter and combust plenty extra proper than warm air so which you're starting to be extra oxygen into your cylinders. in the tip you get extra potential, to no longer point out the sound your engine makes. If no longer something, get a chilly air intake just to make your truck sound ed off! yet they actually do help, you wont word a large difference as you may a swifter, yet you may genuinely tell the more suitable tug.
Well the exhaust might im not sure because some cars (especial luxury japanese cars) are designed to work specifically with back flow pressure. Even though your car is german you might want to ask this question on the bmw forums. In a normal car intake and exhaust dont reduce fuel economy. But they dont add much horse power either. At most youll see a 10-15 gain with headers cats and intake together. The company's make claims of 20hp+ are full of it. Also be aware a cold air intake increases your chance of getting water in the engine. The and after the cats the pipes have to be bigger to increase your flow and your muffler dose nothing than reduce your sound, but it wont make you gain hp. Long story short you wont see any difference in performance for a intake and exhaust.
no it will make it better. better airflow to an engine makes it perform better. its like allowing a marathon runner to breathe easier, they will be able to go further longer.
