Gravana has a stainless cai for the 2.4 on their website that will be available in december but knowing gravana, it will probably cost more than injen or aem. Does anyone know if the injen 2.2 intake will fit the 2.4; is there a difference between the intakes?

yes, the injen cai will fit the 2.4, the same as the 2.2, its already been done on the other site

Thanks, I compared it to my friend's ls and it's the same. I took off the lower intake tube for the winter (it's damn cold outside!)and replaced it with a coupling so that the inlet would stick further out of the engine compartment. The stock tube necks down to less than 2.5 and now its all about 3in. It improved my throttle response and my car seems a little bit faster. I'll buy either the injen or the gravana cai in the spring.
