Impul

Hoshino Impul Co., Ltd., commonly known as Impul, is a Japanese automotive aftermarket company and racing team based in Setagaya-ku, Tokyo. Founded by Nissan's factory driver, Kazuyoshi Hoshino, the company exclusively produces aftermarket parts for Nissans, such as bodykits, engine components as well as wheels.

History
The company was founded in 1980 by the Nissan works driver, Kazuyoshi Hoshino in Maruko-cho, Shizuoka Prefecture. Within months, Impul produced its first product, the IMPUL D-01 wheel, which to promote it, it found its way on Hoshino's Gr. 5 Silvia racing competing in the Formula Silhouette, a Fuji Grand Champion support series, as well as starting a Tokyo-based sales center in Sayama-shi, Saitama-ken. A year later, that was relocated in Kichijōji, Musashino-shi.

In 1983, Hoshino formed Hoshino Racing Limited, a racing team to help promote his products and because of expansion, he relocated his company in Shimorenjaku, Mitaka as well as establishing a depot nearby.

In 1987, Impul offered its first fully tuned car, the IMPUL 630R, a tuned Y30 Gloria/Cedric.

In 2002, the racing relocated to Gotemba, Shizuoka. After that, the company began to focus on tuning cars and has since tuned the Infiniti M, which became the Impul 651S, and the Nissan Juke. Both of these examples of Impul's tuning has changes to the bumpers, engines, brakes, tires, exhaust system, among other things. VIP style is the common element Impul has incorporated on.

Motorsport
Since 1983, the company ran its own racing team which found success in domestic series such as JTCC, Formula Nippon and Super GT.
