-
By pass valve
Maintains an appropriate
oil flow at all times, and opens only when
clogging occurs
-
Elements (2-layer filter paper)
Removes dust completely, and prevents clogging.
The material is thick and more durable
-
Check valve and valve spring
The high spring pressure virtually eliminates
back-flow of oil
Genuine Toyota oil filters are designed
to ensure that the amount of oil supplied
to the engine is appropriate for the engine
type and size
|
|
|
 |
-
By pass
valve
Provides low oil flow only, and allow
dirty oil to reach the engine after
clogging occurs
-
Elements
(1-layer filter paper)
The filtering material is quite
dense. It
removes dust but causes clogging very
quickly. The material is thin and breaks
more easily.
-
Check
valve and valve spring
Spring pressure is only half that of
genuine part, and cannot prevent oil
back flow
Using non-genuine parts
-
A bad element causes clogging, which
will lead to engine seizure and other
problems
-
Engine oil becomes dirty faster, necessitating
frequent replacement
-
It passes on dirty oil to the engine
and wears out the engine faster

 The Air Filter is the lung of the engine
The Genuine Toyota air filter is designed to trap dust while at the same time providing full air flow. Many Non-Genuine air filters are structurally and functionally inferior to Genuine ones, as show below:
|
|
Genuine
|
Non-Genuine |
 |
 |
-
Filter material is needle-punched to increase dust-catching ability by as much as 30%. Its triple layer filtering element has a coarse mesh, medium mesh, and fine mesh
-
Genuine Toyota air filters are engineered carefully to match with engine performance. They perform extremely well and can be used for a long time. Always insist on a Genuine Toyota air filter
|
Needle-punching is conspicuously
missing.
It has only single-layer filtering element.
-
The vehicle will not accelerate properly
-
The engine will consume extra fuel
-
The engine may easily become damaged

 Smooth Operation Brings Smooth Driving
The clutch must be able to transmit power from the engine smoothly when engaging and disengaging and be extremely durable. |
|
Genuine
|
Non-Genuine
|
 |
 |
-
Clutch Facing
Made of a durable heat resistant non asbestos fiberglass and has a groove cut into the facing to prevent faulty engagement caused by suction
-
Hub/Control Plate
Designed for the diesel engine to control vibration and absorb rattling
-
Diaphragm Spring
Chrome plated for excellent durability and has had extensive heat and setting treatments to maintain and even spring load for clutch pedal pressure
Smooth disengagement of the clutch makes for comfortable trouble-free driving.
Outstanding heat and wear resistance assures a long service life.
Vibration and noises are absorbed efficiently
|
-
Clutch Facing
Made of an inferior material and does not have a groove, thus, cannot please properly
-
Hub/Control Plate
Does not have a hub/control plate to reduce noise
-
Diaphragm Spring
Does not have chrome plating and therefore, cannot maintain an even spring load
Using non-genuine parts
Since the no genuine clutch does not perform like the Genuine, the following problems are likely to occur
- Transmission failure
- A shorter service life
- An increase in noise and vibration

 Genuine Toyota brake pads contain absolutely no
asbestos-a material which is harmful to the environment.
However, many non-Genuine product still contain asbestos.
By Company Genuine and non-Genuine brake pads, you can see from the chart below that there is a clear difference in terms of durability and braking power
|
|
Genuine
|
Non-Genuine
|
 |
 |
-
Genuine Toyota brake pads last longer than many non Genuine brake pads
-
Genuine brake pads have a shorter stopping distance than most non-Genuine brake pads
|
Features of
Genuine Toyota brake pads
-
Completely asbestos-free
-
When replacing brake pads, the "shim kit" or "shim kit" and "fitting kit" can be purchased separately

 A fuel filter must meet two contradicting conditions. It must remove impurities completely, and still maintain a smooth flow of fuel.
Genuine Toyota fuel filters satisfy these conditions perfectly.
|
|
Genuine |
Non-Genuine
|
 |
 |
-
High quality resin plastic is airtight and heat resistant
-
Traps particles as small as 10 microns, but still lets fuel through very smoothly
-
Genuine Toyota air filters are engineered carefully to match with engine performance. They perform extremely well and can be used for a long time. Always insist on a Genuine Toyota air filter
|
-
Non genuine parts are not checked carefully, and imperfections in the surface around the pipe connection sometimes cause fuel leakage
-
Some of the non-genuine filters trap dirt well, but the fuel flows through them less smoothly. Others ensure a smooth flow of fuel but do not trap small particles of dirt
-
If they have poor filter paper, they will cause carburetor clogging or corrosion and lead to engine
malfunction
-
If they have
air
tightness problems, fuel may leak and cause fire
