Tweek Performance Foam Air Filters

Tweek Performance Foam Air Filters

1. Air Filter Facts

The Tweek Performance range of performance foam air filters can increase a vehicle’s performance and improve its fuel consumption.

Results may vary from one vehicle to another; we therefore recommend that your vehicle is dyno tuned in order to obtain the best results.

A few of the benefits are:

  • Approximately 10% power gains
  • Improved fuel consumption
  • Directly replaces original air filter
  • Easy cleaning
  • Superior quality
  • Lifetime Warranty

We believe the best air filter for the job successfully balances the following criteria:

  • Maximum air flow – the air filter’s ability to allow air to pass through without causing a large drop in pressure.

  • Cleaning efficiency – the capacity of an air filter to arrest a high proportion of the dust carried in the air, whilst feeding the engine clean air.

  • Dust load-up tolerance – the capability to absorb a large amount of dust, without reducing air flow capacity.


2. Why foam is best?

Wherever you drive, your engine needs the air it uses to be filtered. The technology of Reticulated Polyester Foam give us the opportunity to make an air filter to your exact specification allowing us greater flexibility in design and performance than paper or other air filter technologies.

By using various thicknesses of finer or coarser foams, we at Tweek Performance can vary these three qualities to achieve the optimum result for each application. It has been shown that small quantities of dust particles smaller than 10 microns have no significant effect on engine wear, so the materials used in the Tweek Performance range of air filters have been carefully selected to give maximum airflow capacity, excellent load-up tolerance and high efficiency whilst avoiding unnecessary extraction.  Where high dust flow rates are possible, we tailor the Tweek Performance air filters to arrest even the slightest amount of dust.

The majority of performance filters will lead to an increase in noise compared to stock air filters, however our air filter construction reduces noise significantly when compared to other competing performance air filter designs, a Tweek Performance air filter will probably give more power for longer, whilst remaining quieter than most other performance air filter types.


3. Test Results (Dust Load-up Tolerance)

This test is used to determine the life expectancy of various air filters. It shows the amount of dust that the air filters are able to absorb before clogging.

The dust used is I.S.O. course dust as per S.A.E. test procedure.     


The results of the test show conclusively that the Tweek Performance air filter has a dust load-up capacity of 200% more than the paper element and 260% more than the cotton gauze.  This concludes that the life of the Tweek Performance air filter between cleaning intervals is 260% longer than all other air filters tested, thus making it one of the most economical and cost efficient air filters on the market today.

4. Efficiency Test Results

The indicated test results are the product of tests concluded between paper, cotton gauze and the Tweek Performance foam air filter. The purposes of the tests were to determine the efficiency of each air filter as to the amount of dust the air filters are capable of filtering.
