Takeda you do not have to remove the bumper. I didn't. Stillen you will because you have to trim the radiator support holes

 

Didnt have to remove my bumper for the takeda intakes. Although it wouldve helped
also its difficult to pry the hose into the air duct holes, which is why some say you need to cut, which will help with the takeda install too
i had to remove my bumper in the end because i kept dropping hella nuts screws & sockets and they got stuck on the splash shield underneath

 

Injen probably doesn't need removal

 

what's up bro, I personal have n installed the takeda on my 2013 sedan, while it's not required to remove the bumper it makes the install much easier. Now I'm not knocking anyone saying anything about air flow n nothing being effected but if you dont bore out the section the intake tube passing through then YOU WILL DEFORM N COMPRESS the rubber elbows. I'm pretty sure theres plenty of people on this forum running the takeda with no modification to the section the intake runs through n have no problems BUT!!!!!! The moment I installed my takeda n saw how compressed the elbows where I immediately while out the dremel n started shaving. So it's completely up to you but if you decide to trim n clear the intake tubes then stop at home depot n buy something called "edge guard" n place on the trimmed edges for added protection. Had mine on for about a year n swap the fliter the other day, I didnt have to remove the bumper but I did just to check the rubber elbows n all was good. Good luck buddy.
