K&N Air charger
#11
You won't get any codes.
In fact, your giving the ECM a 'tune', at the same time.
Stock LTFTs, (fuel trims), are Appox: +8 stock , and after adding the K&N pipe + filter, the LTFTs will now be close to 'O', yes , ZERO...
Your gaining 8HP, + giving the ECM, a 'tune', at the same time.
The more mods you have, this intake will help make more gains...
The stock COLD air system is A-OK, as is.
By adding the K&N pipe + filter, you have now created , an excellent COLD air system, for your HHR SS.
My last 3 times at the track, I've been in the 12.5s
This K&N intake system, is a BIG help getting there.
You can't go wrong with this system.
Next year I expect to be in the 11s with the addition of a ZFR.
And the K&N intake system will help me get there...
