이 영상을 위해 10만 km 뛸 때까지 기다렸다! [R엔진 2.0 흡기매니폴드 1]

Additional Explanation The rest will be continued in Part 2. I heard the intake cleaner body and the chemicals used over the past 100,000 km cost nearly 800,000 won. It's difficult to say whether it's good or bad because I can't compare the before and afters under identical conditions. However, as someone who values ​​cost-effectiveness, I wonder if that price isn't enough to get the intake, EGR, and injector cleaned twice. Since the car has been tuned extensively, you'll have to make your own judgment. There was a problem with the RPMs shaking when stopped, but it went away after replacing the intake manifold. However, they say it rarely occurs when going downhill, waiting at a traffic light, or when the engine is cold.
