In terms of registration, an improved intercooler is actually not a problem in combination with factory-charged turbo/supercharged engines. Because it is primarily useful for the longevity of the vehicle. Nevertheless, it can happen that the vehicle produces more power by installing a larger intercooler, even without further changes. That's why it is according to § 19 StVZO imperative after building a larger one Intercooler Also bring a performance chart with you for registration.
enter the intercooler (LLK).
Supercharged engines with intercoolers produce more air density, which leads to better combustion in the combustion tract because there is more space for the fuel with the same oxygen content.
This performance diagram must prove that the vehicle still corresponds to the performance specified in the vehicle registration document, even with the conversion of the LL cooler. To be on the safe side, the intercooler should not necessarily be a no-name cooler and of course it must be installed according to the regulations and firmly enough. At best, the LLK is attached to the top and bottom. With some intercoolers, however, additional brackets must be attached. Tip: Please keep in mind that the performance chart carried is only a few days than for the testing organization.
- a larger/better intercooler changes the exhaust emissions in petrol and diesel engines
- Changes in the emission values lead to an obligation to register the LLK
- an intercooler should have a TÜV parts certificate
Of course, that wasn't the end of it.
