To everyone who has the 2.5l and doesn't want HID or LED conversion kits and simply wants a plug and play LED halogen bulb that performs just as good as the HID and LED , buy the H11 LED 6K PIAA halogen bulbs, even tho they are quite pricy for 299$ , it's the closest match to your LED's and its legal, and best of all plug and play .
