By adding a second intercooler in place of the pipework section, we were able to offer a huge increase in overall capacity to the entire set up without affecting the original (or AIRTEC Motorsport upgraded) intercooler set up.\u003c\/p\u003e\n\u003cp\u003eDespite this huge improvement, the kit fits neatly behind the undertray and can be reverted back to standard with no issues.
