This iconic piece of Bavarian history has made a name for itself as the go-to choice for those looking to step into the world of BMW modding.

This combination of features creates a solid foundation for you to build upon, making it a breeze to turn your E46 into the ultimate driving machine.

You can’t go wrong with the 325i or 330i, equipped with the silky smooth inline-six engines (M54B25 and M54B30, respectively). They pack a decent punch and offer plenty of tuning potential.

However, if you’re itching for that ///M badge, the E46 M3 and its legendary S54 engine will fulfill your high-performance cravings – just be prepared to open your wallet a bit wider.

Now for the fun part: the mods!

The E46’s endless aftermarket support means you can customize your ride to your content.

Popular upgrades include performance air intakes, exhaust systems, and ECU tuning to squeeze out more ponies.

Coilovers, upgraded sway bars, and performance brakes are the go-to options for enhancing your handling game.

The E90/E91/E92/E93 3 Series is a modder’s delight, thanks to its engine options and lightweight aluminum components.

For those looking to unleash its true potential, look no further than the 335i with its robust N54/N55 engine.

This turbocharged inline-six engine offers many tuning possibilities, from a simple ECU remap to full-on single or twin-turbo upgrades.

Or, you can even go for the V8-powered M3!

So, you’ve chosen your E9x and are ready to make it your own.

Where do you start?

Well, you can bolt on performance upgrades like cold air intakes, exhaust systems, and intercoolers, which will give your engine some extra pep.

Say hello to the F87 M2, the little Bavarian that’s always ready to rumble!

Produced from 2015 to 2021, this pint-sized sports coupe shows BMW’s commitment to pure driving pleasure.

With its athletic looks, nimble moves, and talent for leaving rivals eating its dust on the track, the M2 is a top pick for modification.

The M2’s compact size lends itself to a light, agile feel, perfect for slicing through corners. Couple that with its beefy inline-six engine, a close cousin of the M3/M4’s powerplant, and you’ve got a recipe for fun.

The M2 is available in two trims: the standard M2 with its N55 engine and the M2 Competition, boasting the M3/M4’s S55 engine.

Both engines offer lots of tuning potential, but the M2 Competition will really set your heart ablaze, thanks to its robust forged internals and twin-turbo setup.

Popular mods

Eager to unleash your F87 M2? Let’s talk mods!

Kick things off with an ECU tune or piggyback tuner to release more ponies from that turbocharged engine.

Upgraded intercoolers, downpipes, and exhaust systems will help your M2 breathe easier and belt out an amazing soundtrack.

And don’t skimp on suspension and brake upgrades to keep all that newfound oomph in check.

Lastly, to set your M2 apart from the pack, consider splashing out on aftermarket wheels or a carbon fiber body kit.

5. F90 M5 (Best for most horsepower)

BMW F90 M5 CS grey

The F90 M5 is a vehicle that scoffs at the word ‘overkill’! (It’s one of the most expensive BMW models currently in production.)

Starting production in 2017, this sport sedan offers a thunderous 4.4-liter twin-turbocharged V8 with 617 horsepower.

Add in its advanced all-wheel-drive system, allowing you to put that power to the pavement without spinning out like a figure skater.

Finally, sprinkle in its luxurious interior and cutting-edge tech, and you’ve got the perfect recipe for a high-speed, high-class driving experience.

The F90 M5 comes in three flavors: the standard M5, the more potent M5 Competition, and the M5 CS (which has similar power to a Porsche 911 Turbo S).

Both models come with the monstrous S63B44T4 engine, but the Competition variant has a slight power advantage right out of the factory. However, with a few choice mods, either version can be transformed into a tire-shredding monster.

Popular mods

To turn your BMW F90 M5 into a rocketship, begin with an ECU tune or piggyback tuner to unlock even more power from that V8.

To take it to the next level, consider upgraded turbochargers, downpipes, or exhaust systems.

And to truly set your M5 apart from the pack, consider splurging on a set of aftermarket wheels or custom interior touches.

The F80 M3 comes with the S55B30 engine, an inline-six masterpiece.

With its twin-turbo setup and robust internals, the S55 offers ample room for growth!

Popular mods

As always, use an ECU tune or piggyback tuner to crank up the power and torque.

Then, upgraded intercoolers, downpipes, and exhaust systems will help your M3 breathe easier, while coil overs, sway bars, and upgraded brakes will ensure your car sticks to the road like glue.

And to set your M3 apart from the crowd, consider adding carbon fiber body parts or a custom wrap.

If you’re looking for a car that’ll make you smile every time you hit the gas, the 1M is your new best friend!

8. F82 M4 (Best for looks)

Feast your eyes on the F82 M4!

With its aggressive lines, bulging fenders, and unmistakable M presence, the M4 is a rolling work of art begging to be customized.

Its beautiful design provides a fantastic canvas for aesthetic upgrades.

Add to that its powerful S55 engine, which offers plenty of performance potential, and you’ve got a car that’s not only a head-turner but also a neck-snapper.

4 Tips for upgrading your BMW

Are you looking to take your BMW driving experience to the next level?

Upgrading your car can be exciting and rewarding but isn’t always easy.

From finding parts to ensuring you get only the best performance, there are many things to consider for any upgrade.

So, to help you, remember these four tips before starting your upgrades!

1. Always prioritize an excellent maintenance history

When upgrading your BMW, think of your ride as a pet – if you take good care of it, it’ll reward you with love and loyalty (and lots of horsepower, of course).

So, before diving headfirst into the world of mods, ensure your Bimmer has a pristine maintenance history.

That way, you’ll have a solid foundation to build upon, and you’ll know that your ride will be able to handle all the extra power.

2. An engine map is the easiest method to unlock more power

Looking for a quick and easy way to boost your BMW’s performance?

An engine map (also known as an ECU tune) is like the cheat code of car mods – it unlocks hidden power with just a few keyboard taps.

By optimizing your engine’s fuel, air, and spark, an ECU tune can tap into your BMW’s full potential without breaking the bank.

And it doesn’t have to be hard to do it – all it takes is plugging a device into the car’s diagnostic link connector, revealing several engine options from which to choose.

RaceChip is a great company that develops easy-to-install tuning boxes for BMW and most other manufacturers:

Sure, those bargain-bin parts might seem like a steal, but you’re likely to find yourself singing a different tune when your car starts sounding like an asthmatic rhino.

So, do your homework, read reviews, and invest in high-quality components.

4. Don’t forget to upgrade the suspension and brakes

While it’s easy to get caught up in the thrill of adding more power, don’t forget that a well-rounded upgrade plan also includes improving handling and stopping power.

Upgrading your suspension with coil overs or sway bars will help the car’s handling, while upgraded brakes will ensure you can bring all that newfound speed to a stop faster.

Trust us; your fellow motorists (and your insurance agent) will thank you.
