400h Better Performance

[Robl45]

I know the 400h has good performance but was wondering if there are any performance enhancing parts available for it? Maybe another 30 horsepower or so.

I think it is still a bit new for anything like that. I did notice that there is a cold air path through the front hood, directly at the air filter. That design extracts at least a 5+ HP over a non CAI (Cold Air Intake) design. I like it!

well here is another thing you guys can try... take apart the air filter box, there is a first air filter, which seems to be highly restrictive, and remove the piece, there is a second air filter, which seems to be more than sufficient. I also saw a K&N Replacement air filter for the "second" air filter in our vehicles on ebay, for around $50. I'm going to try driving around without the first stage air filter and see how much louder it makes the rx. I will let everyone know of my findings, as im prepared to order the K&N if its not too noisy.
