TLDR: DON'T BUY FROM SNOW PERFORMANCE!

Purchased a new Snow Performance Stage 1 methanol kit # 201 and installed it on my N54 335i 6MT. The install was straight forward with the tank and pump in the trunk. The nozzle holder and check valve setup was annoying to get installed in the charge pipe with very little space to get a wrench on the holder and using the E6000 sealant is a huge mess. The wiring diagram for the low tank LED was wrong and both LEDs burned out once the system was activated.
Called SP and they refused to replace them at no cost, so i bought the correct LEDs and fixed their wiring and all worked. In the process i discovered that the meth tank level sensor does not work either. So far my request for a replacement has not been answered. Do yourself a favor and buy from a different methanol kit supplier. I have had god experiences with AEM in the past.

Pros:
Low cost
Major kit components functional

Cons:
Installation difficulties
Incorrect instructions
Faulty LEDs and tank sensor in kit
Poor customer service
