丰田火花塞 90919-01166 K20R-U 3122 经济型替换装

Toyota spark plug 90919-01166 (K20R-U/3122) fits post-2000 Corolla, Corolla Altis and other models, installed in the cylinder head to ignite the air–fuel mixture, a core component ensuring normal engine operation. Replacement is relatively easy, repair time about 30-60 minutes, suitable for DIY with basic skills. If starting difficulties, rough idle, weak acceleration, or obviously rising fuel consumption occur, electrode wear or carbon buildup are the causes and replacement is needed.
