I want to replace the stock air filter intake, and install one K&N with a Conical filter. Does anybody has one? Really works? I don´t want to spend $300 USD to buy it, and get disappointed. By the way, do you know if the Bosch iridium spark plugs (With 4 electrodes) have a good performance compared with OEM (AC Delco)?

Thanks!

 

I have an Airaid intake system that uses a filter design very similar to the K & N (I bet K & N supplies them). A lot of other companies have copied this screened pleated paper design. It must be good, right? I use K & N's on my dirt bikes. Also excellent! Full thumbs up in performance & function.
Havn't tried the Iridiums yet. Heard they are good. Will try them at my next tune-up.

 

Thanks for your feedback HHR Style! Do you know where i can find it (Airaid)? Your HHR Looks cool!

 

I just bought a kit off e-bay, made a offer of $215.00 and they took it with free shipping. Going to install it tomorrow morning. azoffroadperformance was the seller.

 

Thanks dude. I bought my Airaid online somewhere (cant remember where). Here is the thread I posted:https://www.chevyhhr.net/forums/2-2l-performance-tech-5/airaid-filter-installed-23841/

 

suggest you check socal hhr web site they tested 3 diffrent mfgs. airraid lost HP over stock.

 

Since there have been no dyno charts posted, those results are questioned by many here.

 

I've always had good luck with the AC Delco plugs whether they were for my old Buick V8 (Rapid Fire plugs) or the Irridium plugs for the HHR.I just changed the HHR plugs and have actually noticed about a 1 mpg increase and a little more seat of the pants feel .

 

the socal web. the 3 tested were dyno tests and show actual HP.

 

NO, THEY DO NOT!!!

That whole "test" was contrived and puts out numbers that are IMPOSSIBLE!!

Please, give it up!!
