Hard Alloy
in 1st ring groove
- Prevent wear
- Prevent output reduction
No Alloy in 1st ring groove
- Wear in the early stage
- Engine output reduce
ISP uses hard alloy 1st Ring groove as same as genuine parts so that when the combustion takes place, it will prevent from getting worn by 1st Ring collide with ring groove.
Poor quality aftermarket brand does not have alloy to ring groove so when the combustion takes place, 1st ring collide with ring groove and wear will spread faster.
Thin alloy
- The wear increase around the outer surface of piston
Alloy is used in bottom area of combustion chamber to control piston expansion.
Compare with ISP, alloy that is casted due to prevent heat expansion is 20% thinner.
Have appropriate casting process
- Enough strength & durability of piston
Cast cavity appears
- Increase the possibility of damaging piston
Prevent from piston to get cracked by having appropriate casting process.
Many casting cavities appears so it is easy to get cracked.

Thick Filter Paper
High Filter Paper Strength

Reduce Filter Paper Area
Low Filter Paper Strength
ISP filters feature thick filtration paper for superior filtration strength. This design prevents filter movement during the process, ensuring a smoother and more consistent flow.

SEAL

NO SEAL
ISP filters are equipped with a seal, unlike aftermarket brands. Without a seal, fuel cannot filter properly and may flow into the clean side, potentially causing fuel injector or fuel pump failure.

Inner coating
Protector

No inner coating
No irotector
ISP filters feature both an internal coating and a protector to prevent the cover from colliding with the spring. In contrast, low-quality aftermarket brands often compromise on these features to cut costs, increasing the risk of rust formation and fuel leakage.

There is adhesion rubber so the string and body of the belt does not get peeled off easily.

There is no adhesion rubber so the string and body of the belt get peeled off easily. This will lead to vehicle downtime due to belt breakage.

ISP hardly crack because the cord is thin and has great flexibility.
