Is your classic BMW M50 or M52 inline-6 engine starting to sound like a sewing machine? That annoying ticking noise is often worn-out hydraulic valve lifters. This is a complete set of 24 brand new aftermarket lifters – exactly what you need for a full engine refresh. They're direct replacements for OEM part number 11321739298 and fit a range of 1992-1997 BMWs with the 2.0L or 2.5L 24-valve DOHC engine, like the E36 320i/325i and E34 520i/525i. They come new in the box and are backed by a 90-day warranty. Replacing lifters is a more involved job (you'll need to remove the valve cover and camshafts), but it's a classic DIY for BMW enthusiasts. Once done, it'll restore that smooth, quiet purr your engine is supposed to have. A crucial repair for maintaining performance and preventing further wear. If you're tackling a timing belt service or engine overhaul, this is the perfect time to do the lifters too. A quality set at an affordable price.
