| After performing several back to back tests on my 06 SL, I have come to the conclusion that the stock air intake system is quite adequte for the engine/CVT drive train. After installing a fairly nice K&N cold intake system, consisting of 2 nicely polished aluminum tubes, with the proper slot for the air flow meter, a K&N cone filter and the proper bands to fit the tubes to intake, I started the engine and was nicely surprised how rich it sounded. I backed out of garage,and stepped on it! I heard a rather low end growl that was way to loud and the performance was just gone. The CVT kept dropping down in gear and had no low end power. Needless to say I drove like this for about 3 days to give it a fair chance and then removed the entire system. I put the stock back on, except I left the lower box off. My pick up was almost back to normal and the low end growl was gone. This, too allowed me to see if more air was helpful to allow the engine to breathe easier, no it still allowed the CVT to drop down before it was time. Alas I put the lower box back on and installed a K&N filter to fit in the stock intake filter box and was very delighted that not only did I gain the extra kick I was looking for but the trans(CVT) seems and does shift alot smoother and responsive. I'm selling the air intake system for $75.00 if anyone is interested. |

| Lots of people have various intakes, and I haven't read one story of problems like you're describing. Did you make sure to hook up the PCV hose to the new intake? Perhaps there was a leak? |

All connections were sealed and properly tourqed. I still believe the 06 engine/CVT set up is designed to perform at its highest with the stock air deliverence system. The K&N air filter is a big help. |

In my younger days when we got together to upgrade an "intake" on one of our cars that meant replacing the intake manifold which 99% of the time yielded very noticeable results.
Changing the intake nowadays seems almost superficial, since all you are doing is altering the air filter feed which is upstream of the throttle body and intake manifold. Any increase in horsepower/torque is marginal at best. Many people perceive a power increase because of the increase in engine intake noise. But I guess that is the point. It doesn't have to be fast, it just has to sound fast. I guess that is why you see "fart cans" on Geo Metros and Kia Spectras.

Gripperon, I'm pleased with your answer, as nnjoe figuratively states, "to be loud gets you noticed, to be fast allows you to slip past the madding crowd silently".
PS Do you have any photos of your vehicle in the gallery, I would very much like to see how it is dressed> |

My sentiments exactly, thank you. |

I think there are only two shown and really not very good. Sorry. |

| True there may be negligible increases in performance, but there should NOT be a drastic decrease in performance. |

Exactly! Therefore one should not waste time when the increase in performance is only negligible and leave well enought alone. |

| OF refinement still and more noise does not appeal to a guy that spent many hours adding sound insulation to his MO. |
