Does the Intake Hose Kit for E39 M5 cars need a tune?

No. HPS states that the Intake Hose Kit for E39 BMW M5 models needs no tuning or modification and does not trigger a check engine light. The silicone hose connects to the factory airbox and fresh air scoop, so the rest of the stock intake system stays as BMW built it.

Which BMW M5 models does it fit?

HPS lists part number 57-1291-BLK for the 1998-2003 BMW M5 E39 with the 5.0L S62 V8. HPS does not list it for any other E39 5 Series model, so it should only be ordered for the M5 and not for a 540i or 530i.

What is the hose made of and how hot can it run?

HPS builds the hose from 4-ply high temperature reinforced silicone rated to a maximum of 350F, which HPS says meets or exceeds OE specifications. Silicone stays flexible through heat cycles that harden and crack rubber, which matters on a V8 that is now more than twenty years old.

Why replace the factory intake hose on an E39 M5?

HPS points out that cracked, damaged or collapsed factory rubber hoses are a common cause of rough idling and vacuum leaks. Swapping to silicone closes that leak path for good. A rough idle can have other causes, so it is worth confirming the old hose is split or soft before ordering.

How is the kit installed?

HPS supplies a step-by-step manual with clear pictures, and no modification is required. The job comes down to removing the factory rubber hose, fitting the silicone hose in its place, then tightening the stainless T-bolt clamps. An owner comfortable with basic hand tools can do it in a driveway.

HPS Silicone Post-MAF Air Intake Hose Kit for E39 BMW M5 5.0L

HPS’s Silicone Post-MAF Air Intake Hose Kit for E39 BMW M5 5.0L replaces the factory rubber post-MAF intake hose on the S62 V8 with 4-ply reinforced silicone rated to 350F. Rubber of this age tends to crack or collapse, and HPS notes that a failed hose is a common source of rough idle and vacuum leaks. The kit works with the stock fresh air scoop and airbox, comes with stainless T-bolt clamps, and suits an owner who wants a lasting repair rather than another rubber part.

Design and Performance

HPS claims better airflow and throttle response, but this is first a reliability part. It keeps the factory airbox, HPS publishes no dyno figures for it, and nobody should expect a big change in how the S62 pulls. Its value lies in swapping an aging rubber hose for silicone that resists hardening and splitting, on a car worth keeping on the road.

Features

Integrates with the factory fresh air scoop and airbox to feed cool air to the engine
Smoother path than the restrictive rubber hose, for sharper throttle response per HPS
Replaces a rubber part prone to cracking or collapsing with age
Heavy duty T-bolt clamps in 100 percent stainless steel
No modification and, according to HPS, no tuning required

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.
