Joe so its the tube and the new filter? what is different about the filter box (beside saying Fsport that no one will see)? To me from the pics looks like you are better to get your pipe Joe and change the filter? Seems like an apples to apples comparo!

Looks nice just wondering what more it will do then what I listed above.

Well, the F-sport intake supposedly will have an EO number, so it will pass a smog check in California. That might be significant to california owners planning to keep the car more than 4 years.

Other than that it does appear functionally identical to a Joe Z with a reusable filter and an extra hole in the airbox.

 

^^ Mike you are right on the comparo...

The difference in the lower airbox portion, is that it has been completely smoothed down so that there are no slates inside the air box.. Also, the hole in the front is a very old trick that many Toyota (TRD) / Lexus owners have done in the past.. Cutting out a hole on the front of the air box..
Yes it will just be another air inlet and I would expect the intake tone to increase just a bit more than stock.. Especially with the new filter.. which should flow better than stock...

The box cover is not included, you use the one from your car.


^^ Your pretty much dead on!!!

P.S. - I have an extra airbox in my garage, and I have been experimenting with it to bascially create my own smooth airbox.. Not sure if i want the extra hole just yet, for more sound..

 

Thanks Joe-

so isnt this "extra hole" allowing warmer air from the engine bay? Assuming that its an open hole with with no hose fed to it.

Post some pics please of the box you are working on. I am curious to see please.

 

No problem...

The "extra hole" in airbox concept, is a good question for the F-Sport R&D team..
- You are correct on the fact that it is just an open hole.

Sure, I'll post pics of it when its done... Its just not at the top of my list right now...

 

Is their any way to just get the stickers for the emmissons part, it would be an easy way to pass smog in CA and use the JoeZ pipe, crazy idea.

 

Thats just a crazy idea....

For the record, the pipe swap alone, shouldn't take longer than 10 mins..

Also, as a side note, I passed CA Smog (sniffer & visual) when I owned my IS300..
The smog tech asked me if it was an aftermarket intake.. i said nah, I just replaced the sleeves to Red...

I am interested in the outcome of the new intake compared to the Joez.

I don't really see the benefit of having that extra hole. I always thought they would have another tubing which connects to the original intake air duct to produce more cold air flow.

This will be really interesting to see once someone has installed it and test it.

Right now, I just don't see the benefit of increasing an extra air hole which pulls the air from in cabin. But I hope I am wrong...because why would Lexus introduce a intake to their customers if it decreases the car performance.

 

warm air is more efficient at part load. cold air is beneficial during WOT

i wonder if the extra hole is just for the audio side of the upgrade.

perhaps it's to help with low end grunt with the warmer cabin air during regular driving which most ISx50's face on a regular basis anyhow?

 

to be honest with you guys. the only thing different is an air filter and the pipe. because the pipe isnt plasticy and rubbery anymore you are going to have a louder intake. SO think of it as a typical air intake like the fujita or injen with a black box around it. Im sure it gives you just about the same power as the ones already available but for a more expensive price.

 

Well, I just ordered the intake today, so I'll let y'all know (hopefully) next weekend how it fares.

In terms of the extra hole, it should allow more air flow into the box assembly....assuming that air can get into the hole to begin with, which may be a big assumption.

 

You can buy the stickers seperate, but I think they're pretty expensive for what it is.

 

i noticed in my friends g35 stock air box it has this a 2nd hole as well as the first hole for the air dam.

 

I guess we can wait for Joez to open up an extra hole for his extra intake box and test it!

 

I have JoeZ intake on my car, does anyone have the pix of the second hole of the F-Sport?
I would drill one on my OEM box...and let you guys know...
