F355 custom bmc ota intake

This maybe an alternative to the much more expensive gruppe m intake. The whole intake track is at 4 inches up to the y pipe into the maf. I used a larger y pipe from a mercedes application here so there are absolutely no bottle necks to the intake tract.

The ota system is supposedly BMC's highest flowing airboxes.

The y pipe is VRP for Mercedes

I stand corrected the opening of the MAF is 3.5inches or 90mm. Inside on the lip there's a slight plumbing tape that fits on the lip to get the y pipe to sit snug.

Model numbers for the BMC OTA is ACOTA70/85L200-B

I feel I could have gotten the longer ones ACOTA70/85L230-B which are only an inch longer on the body, but that is fine.

I got a bulk set of clamps if you decide to get them and want some, just send me some postage, and I'll give you some of the marine clamps for the Y pipe to the MAF and the clamps for the filters. I did my own resonator removals as well, and the silicone hoses to remove the ribbed ones to the intake plenum pipes.

I did my test run earlier and so far I am happy!

 

Hello Jeff yes I have some extra clamps. Send me 5 dollars for postage and I can send them to you. I purchased a set of 10 of both sizes so I dont need so many lying around.

It's been running good, I believe it makes the engine roar a bit more. The key is to make sure they're on real tight so it doesnt slip off. I drove for 20 miles the first time and noticed it was slipping back so I reset it and tightened more. 100 miles it has been perfect.

 

I believe the waterproof version has a net around the filter that blocks water from jumping directly to the filter element so it doesnt get soaked. I hardly take the car in rain conditions so I didnt bother getting the wet version. Be prepared to wait on vivid. Originally I ordered from them and after 2 weeks they still couldn't get a confirm ship date so I canceled with them.

I ended up getting from the ebay reseller since they are from Italy and have direct contact with bmc. The filter is made to order so that's why it takes so long, but the seller was very upfront how the process with bmc is and he was 100% accurate with the timelines.

 

The filters come with a bracket which are channel rails and basically you bend them and set the old screw post to hold them up a bit more stable. With the silicone hoses and the bracket they are very much fixed since they also are less than 2 pounds a piece.

 

I'm not sure if its the same seller, he was based out of Italy and always addressed me as friend. I did also try to make an offer once then he just let it expire. It is bit more than vivid but then again vivid couldn't get them at a confirmed date

I believe the guys username has bmc on it so I figured he specializes in them. I did recall he said he has direction connections at the factory. The unfriendliness may come off from his lack of speaking proper english.
