The Accessport is the world's best selling, most flexible, and easiest to use ECU upgrade solution for your Toyota. Unlock power hidden within the vehicle by replacing conservative factory settings with more aggressive calibrations. Follow our staged upgrade path with pre-loaded Off The Shelf (OTS) maps or use custom mapping for any modification level. It's the last engine management solution you'll ever need.

This version of the Accessport includes the capability to flash the TCM which is the unit that controls the transmission. It includes various Off The Shelf transmission tunes which adjust shift points, shift firmness, skip shift behavior, and torque limits to fit your preferred driving style.

This Accessport includes a Gateway Bypass Harness. To use it, connect the harness to your vehicle’s OBD-II port, the Gateway connector, and then to the Accessport. The Gateway Bypass Harness enables ECU communication in situations where the Accessport would otherwise be ignored—such as during initial installation, when dumping an unsupported vehicle ROM file, or when recovering from a failed flash. It is not required for map changes or uninstalling the Accessport. Installation instructions are available here.

Warning! Installation of this Accessport over anything other than OEM or COBB software may result in ECU/TCU failure. Please contact COBB Support if you have any questions.

Why?

The in-cabin mountable Accessport V3 has a large, full color, high resolution screen which allows you to monitor up to six parameters in real time. Fully customizable from the look (multiple bezel colors), layout (set up a race, street or dyno gauge cluster) and mounting options (choose from 1,000s of standard vehicle mounts). Of course, all of the great COBB tuning is included - with enough space for 100 calibrations. This is your new Accessport - and maybe the last one you'll ever need.

Much Needed Cabin Air Filter Replacement!
This Cabin air filter replacement is working well. It had been a long time since I replaced my cabin filter, so this was a much needed replacement. It was easy to do, and a much needed replacement. The air quality inside my car is much better. It smells fresh, and light and airy now.

Best cabin filter I've ever seen
This is the most complex and over-engineered cabin air filter I have ever seen, and I mean that in a good way! The overall shell is a hard plastic, and inside it are two basic parts; the filter (HEPA quality) and the loose fill activated charcoal. The filter media appears to be operating room quality, and if I were to guess, I would say it's like a MERV 14 or greater. The pleats are plentiful, and the spacing of the pleats are perfect, as well as the attachment of the media to the filter frame. The charcoal is a loose style fill, and it fits between the back of the filter media and the filter screen on the very back. This must have 5 times the amount of charcoal compared to the charcoal infused media you can get from many suppliers. The frame fits perfect in my 4runner, and it is hard plastic with good gasket material to further help the effectiveness of the media. All in all, this is an incredibly engineered filter, and if you're the type that wants nothing but the best for your vehicle, you've come to the right place by choosing this one. It is pricey, at $20 for one filter at the time of writing this review, but this is a textbook case of "you get what you pay for." I am going to start only buying these from now on, as they are the best quality and construction filter I have seen, and I highly recommend this filter!

A Simple, Affordable Cabin Filter That Does the Job
I have a mechanic I really trust, which is no small thing these days. The trade off is that he charges a little more for routine services like oil changes, and those visits always include a full vehicle inspection. To manage the cost, I make a point of handling the easy maintenance items myself so he does not feel the need to replace them with higher priced OEM parts. Cabin air filters fall squarely into that category. It takes me about two minutes to replace one, and doing it myself typically saves around fifty dollars. That was the motivation behind picking up this filter for my Toyota Sienna. Right out of the package it fit perfectly. The size is exact, which is important since cabin filters need a snug frame to work properly. There is a clear airflow direction arrow printed on the side, which is one of the two key things I always look for. Without that, it becomes guesswork and you risk installing the filter backward. With the arrow in place, installation is a quick slide and close operation. Functionally, cabin filters are hard to evaluate in real time. You do not get a dramatic change the moment you swap them out. What I rely on instead is whether they fit correctly, whether they load evenly over time and whether they avoid shedding material as they age. Based on construction and feel, this one meets those expectations. It is pleated well and the frame holds its shape. All signs point to it filtering properly, which is the baseline requirement. Because cabin filters need changing fairly often, it never makes sense to overspend on OEM versions unless you have a specific airflow sensitivity or unique environmental need. This filter costs far less and performs the key functions just as well for general use. In my Southern California environment, where dust and pollen appear regularly, I prefer to replace filters on the more frequent side, which makes the lower cost even more practical. The simplicity of the whole process is what I appreciate most. No tools, no struggle, no surprises. The filter pops in cleanly, the compartment closes and the job is done. When paired with the peace of mind of not paying dealership pricing for such a simple part, it becomes an easy product to recommend. A dependable, properly fitting cabin filter at a very reasonable price. Four stars.
