What comes in the Blow-Off Valve Kit for N54?

The Blow-Off Valve Kit for N54 BMW 135i, 335i and 1M contains an aluminum charge pipe with a CNC machined flange, the Active Autowerke blow-off valve that mounts to it, and an illustrated instruction manual with an installation guide. The single valve takes over the job of the two smaller plastic valves BMW fitted to the N54 from the factory.

Does the kit protect the stock turbos when boost is raised?

Yes. Active Autowerke designed the kit so the factory turbos stay protected as boost goes up. When the throttle closes, pressure builds against the compressor impeller blades and can stall them, which strains the compressor wheel and shaft. The large venturi valve releases that pressure before it reaches the turbos.

Will the blow-off valve make an audible sound?

Yes. The valve releases excess charge pressure with a clearly audible whoosh each time the throttle closes under boost. Active Autowerke presents that sound as part of the appeal of the kit. Owners who want the quiet behavior of the factory system should keep that in mind before ordering.

How much power can the kit support?

Active Autowerke states that the kit is proven and tested to handle more than 600 horsepower, and that the large valve opening copes with maximum boost while keeping flow high. That covers well beyond the output of a stock N54 and most bolt-on and tuned builds on the 135i, 335i and 1M.

Is the kit difficult to install?

Active Autowerke supplies the kit as a plug-and-play upgrade with an illustrated instruction manual and installation guide. The charge pipe uses a factory-style throttle clamp at the throttle body, and the one job replaces both the factory charge pipe and the two small plastic factory valves it carries.

Description

Active Autowerke Charge Pipe and Blow-Off Valve Kit for N54 BMW 135i, 335i and 1M

Active Autowerke’s Charge Pipe and Blow-Off Valve Kit for N54 BMW 135i, 335i and 1M trades the two small plastic valves BMW fitted to the N54 for one large-venturi blow-off valve, mounted on an aluminum charge pipe through a CNC machined flange. Active Autowerke has tested the combination beyond 600 horsepower. As boost climbs on a tuned N54, the valve sheds the trapped charge air that would otherwise slam back into the compressor wheels, and it does so with an audible rush every time the throttle closes. The kit does its real work on a car whose boost has been raised; on an untouched N54 the change is mostly one you hear.

About Active Autowerke

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
