my research on dual intakes
I have done quite a bit of research on purchasing intakes and will share my results. Please do not start a flame war I think many are wondering the differences like I was and will benefit from this information.
The bms intake consists of two S&B cone filters with 2.25" opening (part R0633), and aluminum couplers of the same size to slide in the opening on the turbos. The vishnu intake consists of two S&B cone filters with 3" opening (part R0738), and aluminized steel couplers to adjust from 3" to 2.25" opening on the turbos. The filters are exactly the same dimensions except the hole at the bottom, and both have the same list price of around $40 each. The bms couplers are annozied black, the vishnu couplers are powdercoated black. Not much of a difference in either finish to me. Vishnu claims their 3" opening to 2.25" transition flows better, bms claims their 2.25" to 2.25" has less turbulence. They both wind up at 2.25" so I don't see how it can matter. The vishnu setup has different length couplers for fit. The bms directions call to insert the front coupler 2" in to the front accordion pipe and. 1" for the rear coupler. I guess to serve the same purpose. Fit looks identical to me. I came to the conclusion that they are the same. Next to price and shipping. Bms charges $129 plus $34 shipping (I am overseas), vishnu charges $195 plus $100 shipping (and won't take my credit card). For me the vishnu is $132 more expensive shipped, or almost double the price. Not everyone lives here so here are the numbers for US customers from what I gather. Bms charges $129 plus $16 shipping, vishnu charges $195 plus $17 shipping. Bms shipping is 2-3 day service, vishnu shipping is 3-5 day service. So bms is $67 cheaper shipped. Just for fun I emailed a pointed question to get a feeling for character of vendors. Keep in mind I already knew the answer. I asked vishnu if the filters were s&b and they did not respond. I asked bms the same question and within 10 minutes they respond they were s&b filters and even volunteered the exact part number. I thought very interesting. So you can draw your own results. |

I draw two results.
First, insofar as performance is concerned, whatever amount of money you spend on a dual intake setup is a waste. Therefore you might as well spend the least amount. Second, you are a trouble maker and/or a hater. |

Your posts are useless..and didn't shiv proclaim that there was a 20-25 whp gain from these filters? If true, doesn't sound like a waste to me

Why?
Personally, I have been wondering what the differences are. This looks like a decent summary to me Also--I emailed Shiv a few days ago asking some questions about the V3 and the intakes--and no response. I didn't expect something immediately, but as a potential customer, you would hope that the response time would be quicker.

Aren't you the least bit curious why a first time poster makes this subject matter her first post? Could it be a current member or possibly a banned member? Who knows. The culture of hate on this board is palpable. And how is Shiv not answering your email ground-breaking news? |

Ahhhh.....well that could be. I wasn't talking trash--its just that he seems to respond quickly to some things and not so quickly to others. Makes me wonder about being a customer.

the stock airbox proved to be sufficient for stock boost levels on the 335, not sure about the 135?

A pair for S&B filters can be bought for ~ $60 bucks from the source, minus shipping. Couplers are like $5 to $10. Intake gains are so miniscule that spending more than $100 on them is a waste IMO.
It's funny how someone posts facts on here and everyone readily calls that person a hater. For a forum with members owning cars > $40k, you would think peeps would be more mature. |

Thanks for the friendly replies (except lawdude) and I hope people benefit from my research. I figure a US person can buy the filters for around $85 shipped to their door so you pay a premium to get couplers and support. I was just trying to understand the difference between these two products.
For those super detectives out there this is not my first post. I know you will all just check my post history and assume I feel one way or the other based on other parts I have so to present this in an unbiased manor I have not mentioned my other parts. |
