There are several well known brands out there that are synonymous

Manual transmission cars however can benefit from both open pod and drop in filters, as the engine revs easier and the driver can decide when to change gears.This however requires one to drill a hole in the middle of ones bumper.Choosing which one suits you bestOpen pods are generally larger in size and requires the removal of your whole standard air intake unit. It all depends on the type of transmission your car uses. With this in mind, imagine if you place your air intake hose (hose that directs air into the air filter unit) at the front of the car, and at a low position, cold, or in the case of South East Asia, air that is not so warm, can get into the combustion chamber and help the combustion even more, thus allowing better acceleration.Deciding on which to get for your car is simple. Life just isnt fair.There are only two types of air filters available in the market: an open pod or a drop in.Like humans, almost all mannerism of contraptions that has a motor requires air to function.Before getting all excited and deciding to buy a new air filter for your car, take note that aftermarket air filters do allow your car to breathe better, but at the cost of less filtration. Brands such as K&N and HKS are probably the best car air filters money can buy. This does not mean that fitting an aftermarket air filter will damage your engine in the long run. To put things bluntly; more air = better combustion = better acceleration. If you didnt pay attention in basic science class, air is needed to keep a fire burning.There are several well known brands out there that are synonymous with aftermarket air filters. They have the best performance when it comes to air intake, but lacks in filtration capabilities. Air filters with good filtration capabilities usually get dirty faster, meaning that its doing a good job at filtration, whilst a filter with less filtration capabilities would stay cleaner longer. Mind you, it may not be the prettiest of ways. Vacuum cleaners to hair dryers to lawn mowers and yes; cars, all require the intake of air to work properly.In cars, air is required in the combustion chamber where fuel is burned to produce power. Air intake is generally better knitted air layer fabric manufacturers than standard OEM air filters, but again, filtration is not as good. I have seen some pretty well done CAI, but for the most of it, it will look like your car just had a molar removed. An automatic car will benefit from a drop in filter, but will have little or no improvements if fitted with an open pod; the reason being open pods require a rev above 3,000 rpm to be able to perform optimally, and automatic cars generally change gears before the 3,000 rpm mark.A simple test to see how dirty your air filter is and also to determine its filtration capabilities is to simply put it up against a source of light. Same concept here. Aftermarket air filters however are washable, making it a lifetime investment for your car, unless you decide to keep changing filters to test the difference that is. Its called Cold Air Intake (CAI) hoses. All it means is that your cars standard OEM air filter is able to filter tinier dust particles, at the cost of allowing less air through. A clean filter would allow one to see light poking through the pores of the filter whereas a dirty filter would block out the light entirely.. No modifications necessary.Heres another theory: cold air is heavier than hot air, so theoretically in the atmosphere, cold air should be located closer to the ground.Increasing the air intake of your carThere are also different ways to do this.Drop in air filters on the other hand provide plug and play bliss for beginners, as you can simply swap your OEM air filter for these things
