This is a plastic guide rail for the timing chain on the E46 M3, MZ3 S54, and Z4 M (all S54 cars). We have found that on high mileage engines this plastic piece has worn down, especially at the tip. If allowed to completely wear out it could lead to some very bad engine damage as the timing chain flops about and maybe even jumps teeth on the camshafts or crank gear. When replacing the S54 VANOS unit you should also replace this guide rail which is located close-by. A new crush washer is included.

When doing any sort of repair or maintenance there is no replacement for genuine factory parts. Turner Motorsport carries the Genuine BMW brand with pride and has the parts you need to complete your next project with confidence.

This item fits the following BMWs:
2001-2006 E46 BMW M3

Set of 12 ProSeries connecting rod bolts, made by ARP -- the world leader in fastener technology. Each bolt is made of ARP2000 material, which exceeds the strength of 8740 Chrome Moly, and is able to achieve clamp load at 220,000psi. ARP2000 fasteners are used widely in motorsport and drag racing as an upgrade from 8740 Chrome Moly in both steel and aluminum rods. These are simply the best connecting rod bolts available, making them ideal for ultra high performance, racing and forced induction applications.

This set replaces the 53mm length factory BMW rod bolts with part number 11-24-1-713-342 (11241713342) which was used on SOME of the M50 2.5 liter engines from 1992-1995. Check before ordering! Opened ARP bolt kits are not returnable. If your M50 2.5 liter engine has 44mm rod bolts, you will require kit part# 201-6201 instead.

ARP is a company that prides itself on performance and durability, no matter the application. Offering the finest engine hardware money can buy is the driving initiative at ARP and this is evidenced by the staggering amount of satisfied customers and race teams the world over.

These ARP connecting rod bolts fit the following BMWs:
1992-1995 E36 325i/is *** with 53mm rod bolts only ***
