2012 CAI Choices.
Hi, BlackTip12. It seems I'm the resident expert on 2012 XRunner CAIs, so here's my $.02:
I've heard nothing but good things about the URD CAI, but seeing as to how our trucks are still under warranty, the idea of cutting the firewall and having to explain that 'modification' to a dubious service manager did not appeal to me, so, until my warranty is up, I probably will not go that route. YMMV.
I was advised, by several knowledgeable members here that the present generation TRD intake is NOT a good choice for a supercharged engine - and I took them at their word.
After doing some research, I found several folks who are running the afe Stage II CAI with their TRD Supercharged Xs with no problems at all. The problem with installing one on a 2012 is the air pump location on the passenger fenderwell, right where the afe Stage II air box would attach. So, I set out to fabricate a new bracket for the air pump in an effort to relocate in near the power steering reservoir.
ENTER Airaid Products, who produce a CAI for the 2012 X-Runner which comes with the bracket I needed. Being impatient, I purchased the Airaid intake and installed the bracket which relocated the air pump and everything worked great. BTW, the Airaid CAI worked just fine.
Being abundantly cautious with my new 30K truck, I've since removed the Airraid and installed a used afe Stage II CAI I purchased at a great price from a member here because it has been proven, over time, to work flawlessly with the TRD S/C.. It now fits perfectly due to the relocation bracket furnished by the Airaid kit. Zero CELs.
Don't know if my rambling post helped. Hope it gave you some options. Good luck.
