With the increase in the popularity of cars, the denso system has also entered our lives. But many customers are unable to start because they don't understand simple fault codes. When the fault code is displayed on the dashboard, it is not known whether there is a problem with a certain component or the entire system. Finally, most people will choose to hire a professional maintenance master to handle all problems. Without professional tools, it will take a lot of time to troubleshoot problems. Sometimes, the maintenance master will not be able to find the problem without relevant experience. In this way, a lot of our time and financial resources are wasted. Therefore, it is very important for you to understand the meaning of these fault codes. Especially for some minor faults, you don’t need to go to the repair shop, and you can troubleshoot them according to the prompts.

I orderd this gasket kit from VEP because the picture shows the right gaskets kit. with quality gaskets and a reinforced head gasket. the deliverd a gasket kit for a S4Q but low quality gaskets (1 was broken) and the head gasket was not reinforced. so i can not use that head gasket and have to oder a other one somewere else.
Vep sales very good part. Deliver on right time
Good seller
intake gasket was missing
