[13blk335ix]

(2013 bmw 335ix f30 n55) Ive got aFe pro dry s drop in filter, aFe air scoop, BMS exhaust tips, painted reflectors, bootmod3 stage 1 93 octane, have a ER chargepipe ordered and awaiting shipment. I want more reliable power so im looking for ideas on what to do next, I live in NYS so their yearly smog testing is strict. so it keeps me from getting one. I have looked at the fabspeed highflow cat but people have said they do a visual exam. I would be taking it to the dealership for smog testing so I was wondering if they do a visual if there is no cel? so I guess the next upgrade is an intercooler. I don't have plans of upgrading my turbo so I heard wagner is good, but I don't want to void warranty so im looking at dinan. one of my main questions is.... I have the stock non m bumper so which intercooler would work best for the non m mbumper? I don't want to get an intercooler that is too big for my stock turbo or get covered by my bumper. any ideas?
Thanks in advance! (my first post)

What warranty are you referring to? Dinan parts would be the same as any other aftermarket part on your 2013.

For fmic I'd get Wagner Evo I Competition or ATM ( ambient thermal management)

I am not in NY or familiar with that States smog testing but I am a former dealer employee, if the technician or dealer is signing a legal document stating the emissions system is unaltered I suspect they will take whatever steps are needed to confirm that. That's my two cents worth anyway. Good luck!

thanks for the replies, I thought Dinan parts didn't void your bmw dealership warranty? yes I have looked at the wagner evo 1 intercooler I love it, I also just searched the ATM I have never seen it so I will check it out! Another question I have is when I am on the highway around 3k rpm to 4.5 rpm when I am in WOT my car stutters then picks back up, like a hesitation....I have the stock spark plugs on it ( I have the stage 1 bootmod3 93 octane tune)getting the NGK spark plugs and gapping them will this relive my problem? also I have been running stock chargepipe so I have taken tune off until I cant install the er charge pipe thanks

The Dinan warranty you're thinking about runs concurrent with the original 4yr-50000 warranty, which you no longer have. otherwise they have a 2yr warranty on their parts.

the stutter you are referring to seems to be a problem with fuel flow and not your sparkplugs or gap. some run a step colder plug. not sure

i suggest you post threads like this in the appropriate sub-forum for better response

No aftermarket part voids your warranty. BMW can refuse to do a certain job for free if they have evidence that one of your mods caused the failure or damage.

They cannot randomly deny warranty work on unrelated issues

An intercooler is a must when tuning BMW, it does not add any pressure on any other component so it is a safe part warranty wise.
