Tried everywhere to get a cai for my h23 but everybody says its only listed for 2.2 vtec and that the only option is replacement filter surely this has to be untrue. Do I just get the one for the h22a and it will fit my h23 or are they right I can only have replacement filters.....

 

http://www.nolimitmotorsports.com they should hook you up. there are cai's all over the place for the h23. there's also http://www.tornactive.com

 

The H22a1 CAI will fit.

 

They are the same...at least all AEM's are...

 

so if I order the vtec it will definatly fit on. Im from the UK and all stores overhere only list the 2.2 vtec on cai s but list the 2.3 on rep filters. So you rekon go for h22a cai........

 

Yes they are interchangeable between engines but not chassis
5th gen will not fit 4th

 

It will, its just not "perfect".
