Performance modification and usage of higher octane is not about improving fuel economy and saving money its about fun and going faster. Beyond the scope of your intentions with your personal truck. Don’t try and justify your argument because of money saving. The intention is to spend the cash for the thrill. Respect that.
Nothing says I don't. I'm not alone with the utilitarian interests. This one of two Tacoma related forums is more focused on new stuff and understandable.
I'm not arguing against any thread and don't understand your seeming to be agitated. This air box mod is the sort of thing that interests me but for different reasons than others. Somehow thinking there should not be different styles of pickups even if I don't want them really goes against how I think about choice and markets.
Bitflogger I understand you. I think maybe you’re confused with these products being strict improvements of performance and not designed for saving money or improving fuel economy. There may be products and tuners that could develop modification for your interest in fuel economy in the future . I respect your personal preference and your entitlement is totally granted. I do not like having to attack and defend but the thread will go south real fast if it turns into a “is it real or fake“ type argument. The moderator has already kept this thread On the rails once from divulging into a big back and forth.
I apologize if I wasn’t clear in my writing. The mass air flow sensor doesn’t measure measure air pressure drop, but the cooling effect air passing through the MAF/electrical resistance which is sent to the Denso Gen 4 ECU along with ambient air temp values to the same ECU, in conjunction with a differential pressure sensor, in the intake manifold-part #89481-WAA01 for the T24A-FTS engine, makes adjustment for air charge pressure/boost and fuel trim. If the rate of air flow in conjunction with air temp is out of value, then it could be recorded and logged. This is no different than estimating density altitude for aircraft, calculated before attempting take off from an airport at altitude with a prop plane. In 2012- VAG/Volkswagon Audi group Bosch MED9x ECU’s did not log power output, on their B8 chassis, but in 2013, with the Siemens “Simos” ECU, they did. Any automotive manufacturer will have some for of data logging for diagnostic events. When leased VAG “Siemens “sinks” ecu equipped vehicles get their oil changed at the dealer, the vehicle is getting plugged in to look for any anomalies, not necessarily for performance mods, but for unnoticed errors the vehicle is detecting. The data is sent directly to Germany to be evaluated.
Ahhh! True! A mass air flow sensor is restrictive and for stock engines, a very efficient way to measure air flow. For a performance engine-a speed density setup, when done properly- will create more power… but the risk is it isn’t as accurate/precise as a mass air flow setup.
The YouTube video from stillen explains the restriction and how it impacts performance. I am curious how much this box increases noise. I know on naturally aspirated engines, it makes a lot more noise exiting from the throttle body. On my 87 Grand National, When changing the air filter set up, I didn’t notice any noise increase- but the turbo was making lots of noise to begin with.
Any reduction of “resistance” is going to improve efficiency. The biggest gain from a high flow air filter, integrally mounted within an air box to best maximize efficiency is going to improve performance of the induction, but the most gain is when the engine is being flogged, under highest demand, need for higher induction efficiency, compared to cruising in a 25mph school zone. Why wouldn’t K and N filters not show mileage gain? Because the gain may exist, just slight, since most drivers aren’t driving a Tacoma down the Mulsanne @ WOT for 24 hours.
Adding an aftermarket air intake does not void your warranty.
