Refit the air cleaner

Replace the air filter is a high-performance engine intake air to enhance the most convenient and easy way. The role of the air filter is to filter impurities in the air or dust , so that clean air into the cylinder , while the intake noise abatement . Air filter modification does not change the air filter is usually institution only high flow air filter dress , you can dress up the whole air filter , air filter after facelift can make the air flow filtration core speed, the air flowing through the filter resistance is reduced , the ultimate aim is to improve intake efficiency .
    ( 1 ) Dress air filter(range rover turbo)
   ( 1 ) Objective Dress
     Dress air filter cartridge is to replace the original high flow air filter. Original air cleaner element mostly with low cost and intake noise filter paper manufacturing, paper filter surface has numerous holes to block dust and foreign matter , but when the filter surface has accumulated a certain amount of dust , some holes are blocked , the intake air amount will be affected. Thus the original filter requires frequent maintenance and replacement.(saab turbo)
     High flow air filters commonly used high -cost production of cotton or sponge, and with a dedicated oil filter to block dust, since the three-dimensional cotton filter media , dust will be criss-crossing through the barrier layers of fibers , then it float away on the surface of the filter oil filter , unlike paper filter as when holes are clogged with dust after failure. Therefore, higher and sustained high flow air filter intake efficiency . Sponge filters have a more higher cotton filter dust holding capacity , have a longer cleaning cycles , to maintain good air permeability for a long time , there are not afraid of moisture and foreign matter can not be easily penetrated characteristics .
     Dress high flow air filter can reduce engine intake resistance , while improving the efficiency of the intake air and the volume per unit of time when the engine is running , and the fuel supply system of the air flow meter measured intake air increases, the signal oil supplied to a computer (ECU), ECU will control the fuel injector associated with the larger discharge , so more gas mixture into the cylinder , to achieve the purpose of increasing the power output .
    ( 2 ) Dress requirements.
1, the external dimensions of the high flow filter dress must meet the requirements of the original air filter ;
2, the air through capacity must exceed the original filter ;(saab turbocharger)
3 , impurities and dust filtration capacity is not less than the original filtering capacity ;
4 , for convenient use , easy to clean .
  ( 3 ) Dress method .
    Air filter facelift procedure essentials are:
1 , remove the original filter. Open the filter housing , the original air filter out.
2 , clean. The intake pipe cleaner inside the casing and links clean.
3 , into the high flow filter. The high flow air filter cartridge in the original position .
