this link is to the K&N web site. I was wondering if any one has used this or even seen on an hhr. By the the looks of the install page it sits right on top of the motor. Any opions are welcome.

 

I have the Air Aid which is very similair, its great install is easy, any other questions please ask, they have the dyno charts on their web site they claim i believe 8hp which is great at top end

 

Here is a pic of the K&N unit installed on an HHR:



I can confirm it is all plastic and sits on top of the motor just like the stock unit.

Hope it helps,

 

Air Charger? Hmm, sounds fun.

 

Mike is there any heat problems from the motor on the bottom of the box?

 

No, the plastic has been used by K&N on intakes for years. The only issue I am familiar with is that the plastic tubes tend to split after long term use.

I have a friend who got one free from K&N and she is happy with it ("the price was right" she says!)

 

Mike - You're here in SoCal. Do you know what the deal is with it not being CARB approved? Other than just CA bureaucratic stubborness. I can't imagine that it increases emissions, although I supose anything is possible. Or does it just fall under that broad range of "you can change nothing that may in any way impact the approved original smog emissions equipment"?

 

K&N Moved one hose (the breather off the valve cover), and that affects the "emmisions system." By law they would have to go through all the massive beaurocracy and mountains of paperwork (not to mention testing), just to prove that it does not alter emmisions in any way. No manufacturer is going to bother with that - there are so many intakes on the market, and plenty of others to build.

CGS designed their intake so that it does not alter the location of any hoses or sensors - and does not change any part of the emmisions system routing. This allows them to apply (and eventually), be approved for C.A.R.B. exemption status. Generally approval paperwork can take from 6mos - 2 years, depending on Gov. Schwartzenegger's vacation schedule.

In the end, many owners could care less about exemot/non-exempt status. Many simply put their stock air cleaner assemblies back on for required smog checks. (*Often a smog tech will fail you if he's not sure an intake is legal.) That is why it is so important to retain your stock unit for the future.

Hope this helps,

 

How much more noise do you get from the K&N and CGS? Is it mostly under WOT?

 

Yes; most power increases are realized at WOT, during passing gear sequences, or while entering freeway onramps.

However, driven conservatively, you can see a 2-3mpg increase as well.

It really works well both ways!
