I was wondering since Lexus Is250 F-Sports is my first car. It is leased and I really want to lower the car, swap out intake and exhaust with aftermarket. I was wondering if that would be a problem when I give it back to the dealer after the lease is over? Would I have to swap back all of the parts back to OEM? and that wouldn't be a problem?

 

You can swap everything out as long as you put everything back correctly when you return the car.

 

Thank you for the fast response I'm probably going to start with intake and rs*r downs.

 

Go with the GReddy intake. Mine sounds AMAZING!! Also for springs, do you plan on going with bigger wheels or keeping those stock? If you stay on the stock 18" wheels, go with the Super Downs. The people who have them on their stock wheels love them and the ride is amazing. I am getting my Down Springs tomorrow but since I have 20" wheels, I couldn't run the Super Downs. The ride quality is supposedly superb and the look of them in really nice.

 

I always say go with original lexus parts. then you never have an issue that will not be covered under warranty

 

Thinking of Greddy intake too or maybe Joe Z intake with Joe Z axle back exhaust.
Think i'm going to stick with the stock 18" and put on a super down.

He said he used a spacer do I need to use a spacer for it to fit?

 

I have thought about that, but original parts are so expensive...

 

If you are into a loud growl noise, go with the GReddy. The JoeZ is really good but most people find it way to quiet. I guess that is the purpose of Joe's intake, to eliminate all sound. You don't need spacers to fit superdowns but if you want to get them, they look really good on his car.

 

If I can find a new/used GReddy locally i'll go right now to pick it up and probably while at it, i'll grab an axle back from Joe Z since i'm at Socal.
Sorry to keep on asking but what is the benefit of having spacers? I like the setup on the other post with 20mm spacers all around with stock wheels and super downs.

 

I think they're just used for looks. The wheel pokes out a bit more.

 

before you do so, re-read the lease agreement about modifications to a car. Sometimes they dont allow you to

 

Thank you so much for the heads up.

 

If you go through the build threads and look at RastaRacer's car, his is leased and he has done plenty of mods. I don't know if it is different for each dealership, but his you could mod. You just have to be careful that they don't cause any problems because Lexus won't fix it.

 

which Greedy that will fit to 2014 IS350F?

 

From what I read throughout the forum was GReddy from 06 - 13 fits all 2014 350F and 250Fs. From my knowledge tho.. Correct me if i'm wrong.
