If 300 horsepower is good, 320 horsepower is better. And when that 20-horsepower boost comes at a cost of just $599, it's really a no-brainer as far as we're concerned.

BMW hopes you agree, as it's officially announced two new Power Kits for the 135i, 335i and certain X6 models that boost the power of the 3.0-liter turbocharged inline six by the aforementioned twenty ponies. Just as welcome is a boost in torque from 300 to 332 pound-feet (when equipped with an automatic transmission) and 317 lb-ft (when equipped with a manual or DCT transmission).

The increase comes courtesy of what BMW is calling Version 1 Power Kit, which basically amounts to a reflash of the car's computer system, and it can be applied to any 135i or 335i and all X6 models produced before April of 2010. These power figures bring the turbocharged machines up to the specification of the 2011 335is.

A second option is the Version 2 Power Kit, which adds an auxiliary water cooler and "enhanced" radiator fan to the reflash on 1 Series and 3 Series models. The V2PK costs $1,199, a modest increase over the $599 of Version 1 considering the added hardware. Both kits also include an "exhaust burble sound during engine overrun conditions." BMW is quick to point out other modifications may be necessary and that installation isn't included in that price.

In case you're thinking this all sounds rather familiar, BMW did indeed make a similar announcement a little while back. While that press release heralded the option for new buyers of the 2011 335i, this one indicates the availability of current owners to get the upgrade retrofitted to their cars while their warranties remain intact. For all the details, hit the jump for the press release.

      Burger Tuning JuiceBox is ~$500 and more than doubles the power gain that they are quoting. Of course, if you are concerned about maintaining your factory warranty, the BMW option is better.

      Jeremy, if you think $1200 for a CPU reflash, water cooler and radiator fan (plus, what, another $200 for installation?) is reasonable, then you must be making a lot more money than the average blogger.

        $200 for installation of V2 kit, it'll be closer to $500.

      bmw once u mod the software with something aftermarket & if the dealer detects it they void the warranty on your cars power train. meaning they won't cover High Pressure Fuel Pump (bmw has made 5 revisions last time i checked) , turbo problems,*and other bmw problems that tend to pop up. A good service writer buddy of mine is notorious for doing this to our local audi tuners at his dealership, basically the tech detects a change in the program during the inspection (they plug you car into an obd2 reader as part of the oil change/ service) and then he generally per dealer policy black lists that cars warranty for power train claims. I've heard of local bmw dealers doing the same for so called undetectable flashes. if it was my money i'd get something bmw covers versus worry bout my cars warranty dissolving and me having to cover a hpfp or some other problem w/ the car when its under warranty.

      There are aftermarket tuners that will get you 40rwhp for $599, so I don't see the advantage of this.

        The warranty, that is one, and probably the only advantage of this.

      $600.00 for what amounts to a software upgrade? Yikes.

        That is a douchey show and Speed Channel sux. Also you are spam, and thus have been reported. But at least you are kinda relevant, so I will upvote you as compensation for reporting you. Peace

      Your not really going to notice 20hp. You will notice your wallet being $600 thinner.

      $599 is not bad for a power upgrade that is covered by the manufacturer, I will definitely call my dealer and see what the total cost is before deciding.

        While it's not an exceptional deal, it's certainly not terrible, either. As mentioned below GM charged around the same for 10 more hp than this gives to the 2.0T ecotec motors. It's not like you're going to typically get that gain by spending 200 bucks, unless you believe all the claims that adding a K&N "cold air" intake that ends up ******* hot air in is going to give you 20whp gains. The nitrous suggestion is kind of stupid, apples and oranges. Not like you can use that in daily driving whereas this is an all the time available upgrade. One is only going to use nitrous if they go to the track and drag their cars. Unless of course you're an a$$hole that street races. Again, not saying this is a slam dunk great deal, but adding power costs some money.

      Heck - that's worth it for the "exhaust burble sound during engine overrun conditions" alone.

        Damn stupid commenting system. I was going to say the following: This would be something that any other automaker would issue a TSB for; just updated programming to the existing vehicle to fix issues or to just make the car perform better overall. Really what I'm getting at, is that BMW really shouldn't be charging anything to flash updated engine/transmission programming to pre-existing vehicles. Note that this is DIFFERENT than dealer offered "tunes" that increase horsepower like the GMPP tune for the Pontiac Solstice/Sky turbo that increased power output from 260HP to 300HP. I could understand if that was what BMW were offering, but this? Come on now.
