Past Customer Review:

" My recently restored Land Rover Defender (300 TDI) was upgraded from the stock intercooler and turbo to Unicorn’s intercooler and Falcon’s turbo.  East Botha of Lekker Defenders installed them and noted that Unicorn’s was notably larger than the OEM. The truck has not been been on a dyno, but has more power and I get maybe 2-3 more MPG. Unicorn’s customer service is responsive. I have not noted any decrease in reliability. Unicorn’s was in stock while a more known UK brand was out of stock when I bought. "
