Throttle body spacer
Was trying to read up on some easy bolt ons to improve performance, and came across throttle body spacer. Does this really improve performance? Anybody did this, and are there any issues with doing this?

Honestly, the only benefit will be a cat-back exhaust for minor gains. You can do the downpipe which will gain you more, but true benefit is with a flash tune like BM3 or MHD.

I was trying to see if there are any easy bolt on's to get some modest gains without tunes. Only looking to get 20-30whp but doesnt look like there are many options.

IMO your best bang for the buck by far is the BootMod3 Stage1 tune. Smooth and powerful like it came that way from the factory. |

If you use an oiled air filter (like K&N) be very sure to follow the instructions because getting oil on the MAF is not a good thing.

Have you thought about lighter wheels? It doesn't exactly add HP but it would free it up.

Thank you for the input guys! Looks like a tune is a better bang for the buck rather than the bolt ons I was looking to Add. Waiting for the warranty to expire.

Why? This comes up all the time. I used to feel the same way, until someone basically said: If you mod out of warranty, you have no chance of anything getting covered. If you mod in warranty, you at least have a chance of getting something covered. It's not like the tune has less of a chance of causing any problem after your warranty expires lol.
Just my 2c. Everyone's risk tolerance is different. Also note that tuning doesnt impact your warranty at all for anything unrelated to tune. Also note that technically any non-BMW/unapproved modification can impact your warranty for something BMW can say the mod caused. Boltons are in that category. |

Yes, stupid easy to do (under 30 minutes of your time). All you need is the enet to OBDII cable, and a computer. You probably can do it off mobile as well (just never tried).
I wouldn't waste your time/money going to a shop. For me, buying the license, to receiving the email to finalizing the update was 30 minutes -- on a sunday! |

Further still, there is a ACN map for those of us with terrible quality 91 (AZ, CA, NM). |

You can go through the ones listed above, but I personally prefer direct vs middle man if I can. |
