1999 Cat 3406E
We have been taking my Cat to the dealer for years on a running issue and that entire time no one could fix it. Immediately after (the AirDog) installation, the motor idled better and was more responsive. The very first run I gained .8 mpg and the power gained was amazing. Plus the problem I put up with for years was cured! Everyone needs to know about this product.
