■商品概要The material is ABS plastic. no heat accumulation Does not shrinkat high rpm■詳細説明It can be attached to the throttle. and the original air filter，noneed to bend the other brushesBy removing the original air filterpipe and installing the KSPP horn instead，it can clearly increaseengine efficiency. MakeER6n more powerful.A horn is a trumpet-shaped device or a horn of different lengthsthat fits into the air inlet in the intake system of a carburetoror throttle engine. It is designed for1. Let the air flow into the inlet smoothly and evenly with a flowstream attached to the pipe wall called laminar flow.2.It can adjust the dynamic range of the intake tract by acting asa resonant tube，which can adjust the frequency of pressure pulsesalong the length within the tract. (can increase torque，horsepoweraccording to engine rpm same principle as exhaust pipe)■注意点※取扱説明書が付属する場合は外国語となります。※画像には他のカラー、商品が含まれております。※メーカー都合により商品の仕様変更がある場合がございます。ご了承ください。　※画像はイメージです。■適合車種ER-6n ER-6n
