*Please confirm whether your car has an OPF system before placing an order.The BMW 3 Series adopts a new EfficientLightweight body structure, which can increase body rigidity by 25% and enhance key components by 50%.
The front suspension tower, engine auxiliary beam and hood are all replaced with aluminum alloy. With other details, the weight of the whole car is 55 kg lighter than the previous generation.
In addition, the wheelbase is longer and the tire grip area is larger. BMW always maintains a 50:50 weight. The BMW G20 / G21 is definitely a good car worth have. However the M340i is too mild in terms of exhaust noise. This is not to say that the 3.0-liter TwinPower Turbo and 374hp/51kgm are not enough, but the 840i and GR Supra are also equipped with the same B58 engine, they sound so fierce and exciting, and the M340i sounds without personality. In fact, the exhaust sound is tamed or mad, which is more affected by the ECU adjustment, and the exhaust system will only make the effect more obvious. The catalyst for this car is a 200-cell Sportscat. If you choose no cat, the fuel content in the exhaust gas will increase, which will make it easy for the exhaust gas to make interesting sounds, such as POP&Crack.

This stuff works!
Size: 32 oz
I was sceptical but wanted to avoid replacing 2 rear tires on my zero turn mower. The tires were leaking air and had bad sidewall cracking. I found the use of the product to be easy and quick. I aired up the tires and rode around the yard a few minutes to distribute the product in the tires. It has been 4 days and both tires remain aired up. Previously both tires would already be flat within this timeframe. Excellent results for me!

Doesn’t work for a car Tire seal slow leak
Size: 16 oz
Does not work for a car tire. Had a slow rim seal leak. Out 32oz in still leaks the same. Do not buy. I got the one with fibers in it. It worked just fine. This does not work. Period. $30 wasted actually I purchased two so I wasted $60 when I could’ve bought probably a new tire

#1 Tire Repair
Size: 16 oz
This stuff is Fantastic. I have a riding lawn mower and one of the front tires, which is small, had been running low for a couple of years, we took it off. to fill it with the liquiTube and you could see cracks all around the outside of the tire. The liquid tube oozed out of one of the cracks and sealed , immediately. My brother rolled the tire around real good before we put it back on the track lawn mower. It has been 3 days now and today I mowed for 1 1/2 hrs and the tire as full as it was the day we put in the LiquiTube. This stuff is fantastic, it really, really works!
