Not sure what you mean cuong, but if its regarding the 3A racing pod with my INjen CAI then 'yes', still no CEL. Been pushing it a fair bit too. I got the cleaning kit and i oiled mine, tomee didnt oil his so i dont know if thats the varying factor. But yeah still going strong baby! Best buy ever! Big thanks to duy aka Kenshinx for the idea and getting it for me! If you do get it, get 2 so you can keep cleaning and reusing them.
