All auto filters are designed to prevent harmful debris from
entering any parts where air and fluid flows, including your engine, radiator,
fuel lines and more. Once a filter is no longer performing its intended
function, decreased performance-even engine damage-can result.
When your air
filter is dirty, your engine is forced to work harder, resulting in poor fuel
economy, higher emissions and, possibly, a loss of engine power. In turn, as a
worst-case scenario, a clogged Cabin Air Filter can lead to under-performance
of the A/C system, causing weak air flow from the cabin vents. It can also lead
to unwanted, unfiltered air in the cabin. As for a mucked-up fuel filter,
that`ll land you with a weakened fuel supply to injectors, a reduction in
engine power, poor acceleration and lousy fuel economy-not to mention a
potential breakdown.
They protect vital
car parts by keeping harmful debris at bay so your car runs right. Filters also
ensure your car runs more efficiently. The cleaner your filter, the more it
allows for the maximum flow of air or fluid through the system. Like a clogged
drain, a dirty filter starves the system of the vital air or fluid and makes
each system it protects work harder to do its job. Once filters are dirtied,
they should be replaced.
it`s recommended
that you get your filters replaced every 12 months or 12,000 miles, but check
your owner`s manual for specifics about your vehicle`s filter replacement
schedules.

Key planning
On August 29th, Zhen Mingli (1868.HK), which was listed in Hong Kong, closed at 83.51%, and its main factors were:
1) Subsidiary Heshan Yinyu Lighting Co., Ltd. won the bid for the indoor lighting LED downlight project in the “2012/2013 Annual Financial Lighting Product Financial Subsidy Promotion Projectâ€; 2) Announced on the LED modular production mode on the same day.
 The High-Tech LED Industry Research Institute (GLII) believes that the transformation of Zhen Mingli's production model does not have a unique competitive advantage, and the role of the company's revenue and profit growth in this year or in the next few years will be very limited. The change in the modular production model of Zhen Mingli and the resulting large fluctuations in stock prices have made investors more rational.
The performance and operation of LED chip listed companies in the first half of the year mainly have the following characteristics:
1) The leading performance of the revenue leader is outstanding, and the net profit declines comprehensively; 2) The downward trend of gross profit margin may continue, the net interest rate will rebound and the capacity will be further released; 3) The price of the product will fall but the sales will not be smooth, and most of the inventory will increase, and the accounts receivable will be increased. The number of turnover days has increased.
GL GLII believes that domestic LED chip listed companies will still face the pressure of price decline in the second half of the year. The competition for product competition, especially the sales channel competition, will continue to increase due to price decline. The industry leader with scale and brand advantage will be in the long run. Will maintain a competitive advantage. 
ïµ High-tech observation
GL GLII: It is more difficult to catch up with sapphire. Silicon-based GaN substrate mass production companies are trying to get rid of the monopoly. GLII: The Japanese lighting market is suddenly braking, and Japanese businesses may face “white busyâ€.
