It's not about Airtrek but more in general. My Airtrek comes with clear windows (local USF car), but I've tinted the rear doors, rear side panel and rear windscreen 75% tint. Using it for 4 years now, no problems...
I am wandering which one is the best air filter in the market. HKS, Apexi, Blitz, K & N, Greddy and others guys please share your thoughts and experiences.
I have some serious question wanna ask u Si fu ~
Mine is oil temp meter ~ but the problem is !!!
i read from the manual itz say only water temp need to cut hose between the radiator and engine then put a adaptor...
