Hey, good for you, we've had ours for a year now and have no regrets.
The only thing we've had was the fan temp. sensor in rad. went out, but that's a known issue, I think the new ones are an updated one, I had previously done NMK's fan bypasss mod. so we had no problems.
First thing to do is replace factory air filter with a uni or twin air.
And for convenience in case fan sensor goes out do the bypass mod.
We really love ours..
