9 Maintenance Tips to Improve the Performance and Driving Experience of a BMW M3

When it comes to sports cars, one of the most popular in its class for style, speed and even price range is the BMW M3. Be that as it may, the BMW audience always seem to be a bit extreme. They either love the idea of the M3 or they hate it… no in-between. That essentially makes this BMW one of the most controversial cars you can own.

The truth of the matter is, the BMW M3 is one of the best cars manufactured to-date. If you’re among the group of skeptical or dissatisfied BMW owners, chances are you purchased a car with low-quality and/or poorly-maintained parts, probably because you were more concerned with price versus quality.

You see, the key to being a happy BMW owner is easy… take good care of the car, and keep the M3 parts running smoothly by sticking to the maintenance schedule. As the saying goes, keep it “firing on all cylinders”.. When issues arise, handle them. If you happen to be a BMW M3 lover, you know there is no other automobile that affords such a great driving experience. To continue to experience that amazing ride every time you’re behind the wheel of your M3, here are some BMW parts maintenance suggestions:

1.  Only purchase M3 parts from a trusted vendor. Whether you intend to do most of the car maintenance, modifications and repairs on your own, or go to a professional mechanic, it’s imperative that you only purchase your BMW M3 parts from a trusted vendor like eEuroparts.com. Faulty parts – or worse, fake M3 parts – can lead to serious issues with the engine resulting in the deterioration of your beloved bimmer a lot sooner than you might’ve anticipated.

2.  Change the oil (fluids) once every 4500 miles or so. Make sure that you use genuine or OEM quality-grade oil – preferably synthetic – or it won’t stay effective for more than 2,500 or 3k miles. Running degraded, broken-down oil through your M3’s engine is almost as bad as running it without oil at all.

3.  Change the oil filter at least every other time you change the oil fluids. Even if you have new oil fluids, a sludgy old oil filter may contaminate the new oil – that is if the filter can even do the filtration process. A new oil filter will cycle the oil fluids better so the engine stays lubricated better, not to mention keep the new oil cleaner so it actually benefits your engine for longer.

4.  Air filters should be cleaned or replaced at least every few thousand miles. Your car’s engine may benefit from a new/clean air filter more often depending on where you live, as there could be a lot more dirt and pollutants in your area than in the air in other areas. You can easily open the air filter box yourself and check to see if it needs cleaning or replacing.

5.  Change your fuel filters every 20k miles or so, depending on the cleanliness of the gas you’re using. Dirty fuel filters can lead to fuel injection delay and even loss of engine power, which are two things you especially don’t want when driving a car as smooth and powerful as BMW’s M3.

6.  Check spark plugs periodically. Every BMW M3 leaves the factory with performance in mind and the biggest changes you can make to the spark plugs are their heat range and voltage. Based on your engine’s settings the ideal heat range will rise or lower, therefore if your M3 remains stock then you are fine replacing your spark plugs every 100-thousand miles with a new set of stock spark plugs. However, if your M3 has performance upgrades you’ll want to test it out to find the appropriate heat range that your specific bimmer needs, which will tell you what performance spark plugs are applicable to it.

7.  Pay special attention to the cooling system overhaul – One of the most important maintenance jobs for the M3 is the cooling system. Many BMW M3 owners complain that their car overheats frequently, and in many cases this is the reason why. Make sure to have a mechanic perform a complete overhaul of the cooling system’s parts. Check your owner’s manual for the exact mileage that warrants that repair, or you can simply inspect the system’s parts yourself to see if any of them are damaged.

8.  Check your intake boot for leaks. A leaky intake boot is one of those auto parts that can cause the check engine light to come on. This is a direct result of bad air and/or fuel intake, meaning there is not enough reaching the engine. You’ll know it’s time to check your M3’s intake boot if you notice rough idling, weaker performance and/or higher fuel consumption.

9.  Clean your sensors. Your idle control valve; oxygen sensors; fuel injection pump, valve and sensors; and mass air flow sensors are all electrical parts that need to be cleaned, and sometimes replaced. Many car owners make the mistake of forgetting these electrical parts, which is a huge mistake because they keep your car running extra-efficiently. When they are clean they improve your BMW’s overall top-performance and fuel-consumption.

You might look at this list of parts repairs and upgrades for your BMW M3 as a waste of time. Contrary to popular belief, ALL vehicles – even the performance-driven M3 – require a great deal of maintenance for them to drive well. You really shouldn’t run into many issues as long as you stick to the BMW maintenance schedule, pay attention to any warning signs, and purchase your M3 parts from a trusted store. If you’re not the greatest with handywork, it may be a good idea to work with an auto mechanic who specializes in BMWs. You can even buy your M3 parts online and bring them to the shop to install for you. They’ll ensure that your bimmer is properly maintained, so that you can continue having the best driving experience ever.
