Säker en liknande avskärmning till mitt öppnafilter. Helst i sverige. Bild --> Länk Min vinter bil: Länk /Daniel | |

Jag också, fast till e46 coupé. BMW CS #5206 |

| Bocka till av en bit plåt bara, inte svårt | |

Jo visst kan man bocka till en plåt, men det är ju inte så snyggt. Tycker installationen på bilden ser bra ut. Min vinter bil: Länk /Daniel |

läs detta och begrunda, skrivet av Wayne på Länk som håller på med en bok och av erfarenhet vet jag vad han pratar om, lite långt men intressant ============================================== There’s been a lot of talk on Internet chat boards lately about cold air intake (CAI) systems. Some manufacturers will swear up and down that there’s hidden horsepower in the intake system. Other ‘experts’ claim that it’s total bunk – a myth that has easily circulated in the age of the Internet. I personally believe that the truth is located somewhere in-between. On some BMW models, a properly engineered cold air intake kit can effectively cool the intake charge entering into the cylinders. Why do you want this in the first place? Cooler, denser air will move the engine further away from detonation, and will also deliver a denser air charge which corresponds to an increase in horsepower. First of all, the BMW E36 intake system is indeed a cold air intake. It sucks air from the outside and insulates this intake from the heat generated by the engine. Where it doesn’t work too well is in the area of airflow restriction. The stock system is somewhat restrictive, and makes the air work its way around in order to enter the engine. Aftermarket performance intakes serve two purposes – to better inject colder air directly into the intake system, and also to reduce the restrictions that are inherent in the stock system. Just how much horsepower can you expect to gain? It all depends on your particular BMW model and which model kit you use. It is possible that a poorly designed kit used with an aftermarket air filter will actually create more restriction in the intake, and cause a decrease in horsepower. In addition, a poorly installed intake system with leaks will also decrease performance. I have seen dyno tests where the installation of an intake system has done nothing, or has even reduced horsepower. Then again, I have seen other tests where significant gains of about 10 HP were recorded. The bottom line is that a performance intake system is a (typically) expensive aftermarket add-on that may increase your horsepower slightly. Some kits cost over $500, which translates into a very high dollar per horsepower ratio. Some other kits are less expensive, and incorporate reusable aftermarket filters. While I’m not a huge fan of these filters as then tend to filter less than the stock ones (see Project 3), there can be some costs savings in the long run from not having to buy multiple stock air filters. Perhaps the only thing that the can agree on is that a performance intake system will often give you a much better engine growl at higher revs. I’m personally a huge fan of growling noises, so this would certainly be a plus for me if I were making the decision to install one of these systems. For those of you who prefer a quieter engine, you might be slightly annoyed at the new music your engine is playing. There are two distinct types of systems available on the market. One is the short ram which is located in the top of the engine compartment and uses a heat shield to block heat from the engine. The filters are easy to change on these types of systems. The other type is typically referred to as a cold air intake and uses long tubes that connect the intake to inlets in the front bumper. These systems capitalize on the air pressure available at the front bumper, although the filter is difficult to reach for changing or cleaning. Also, if your intake is low to the ground, you must be very careful not to go through any deep puddles, otherwise water may get sucked up into your engine intake (also referred to as hydrolocking your engine). There are literally hundreds of manufacturers of these products, from the large tuning companies to people selling homemade kits on eBay. If you are going to install one of these on your car, I would do your research first, and stick with a well-known manufacturer. I’ve personally heard good recommendations from people who run kits available from Dinan, East Coast Induction Systems, Cosmos Racing, and Advanced Flow Engineering. ################ As you can see, I'm not a firm believer in them. I believe your money is best spent elsewhere? -Wayne |
