RC 350 F Sport Enhancements

Hi everyone!

I recently bought an F Sport after driving a number of competitors. I fell in love with the red interior and the ride of the RC. The one thing that made me second guess the RC is the performance. It doesn't have enough on the engine side for me. I bought it despite a 0-60 that was less than stellar.

I want to do some after market stuff to improve my RC on the horsepower and torque side. Does anyone have any advice to increase the muscle in the RC? Turbos to recommend? I am primarily focused on the power side of things.

Best,

Best,
There are not that many aftermarket parts for these cars... The only thing i have seen is the Takeda Intake for the 2014-15 GS350. Its a direct bolt on fit.

Other than that everything else that i have seen is custom made.... Custom Exhaust... I'm pretty sure you can installed a custom turbo charger too...

Eventually we will get a nice kit available for this car...
How much more power are you looking for in the RC?
Depending on how much you want, how you go about increasing power will change. If you want under 50hp more, a combination of bolt-on's and an ECU tune could accomplish that, anything more and you'll likely have to go turbo.

Do you know anybody who is doing ECU tune for this car? Doesn't the RC 350 have the same engine as the IS350?
I would throw in a full exhaust system, air intake, tuner, turbo and suspension.
I'd say 100 more hp would be good enough to feel what you want out of your RC performance wise.
there's this tune for the IS350 that i recently saw, but can't confirm if it's something that can also apply to the RC

I spoke with Vivid Racing about a tune as they are located in my town. They said their tune is the same for the IS350 since it has the same engine. The price is a sticking point as it comes in at $700.

Even their tune will only add about 20 horsepower, per their website. As with any tune the emissions will not be set (ready), and before an emissions test the vehicle will need to be put back to normal to get everything ready. Just an FYI.

Afe Power has a new Takeda intake specifically for our cars as I got the first one. It is now listed on their site. Lexus RC 350 2015 - aFe Power

I wonder what is the actual difference between the dry filter and the other one... White vs Blue...

The dry filter when cleaned just has to have the dirt gently knocked out of it, and then vacuumed out.

The wet filter, is just that wet, but with an oil. When the wet filter is cleaned you can use the "special cleaning agent" or like I do I put Dawn in a bucket of hot water, put the filter in and let it sit for an hour or two to dissolve all the old oil. Skim off the junk, and remove filter, and run clean water over the filter, but not high pressure. Let air dry for a couple of hours, and reapply the filter oil, which is gently sprayed on the filter. Reinstall filter and you are good to go for another 10,000 miles or so depending on where you live.

NOTE: Putting too much oil on the filter will eventually get on the MAF sensor, which is not good.

I've only had Wet filters on any of my cars and like them better than the dry.

I got the following explanation of Oiled vs. Dry.

In general (not one specific brand) here is how it usually shakes out:

A) The typical DRY high-performance drop in air filter is able to trap slightly more contaminates (99%) due to the smaller micron size of the cotton gauze material used, but this also restricts the overall FLOW rate of the filter. The cfm (cubic feet of air per minute) is less than oiled filters of the same size.

B) The typical OILED high-performance drop in air filter is able trap slightly less contaminates (98%) due to a larger micron size size of the cotton gauze material used, and this improves the overall FLOW rate of the filter. The cfm is more than the dry filter of the same size.

Wet or Dry air filter? dont understand

I hope this helps.

I've always had the Oiled Filters on my cars. K&N drop in and JWT Pop Charger Oiled Filter... I've just been intrigued by the Dry filters.

Great Explanation!!!

Thanks buddy.

No problem. The oiled ones are much more work, but IMHO I think they are worth it in the long run.
bump this thread to the top;)

Apparently they're supposed to help with filtering out small particles. One thing for sure though, the process of oiling your filter is cool, makes you feel like you're doing something special for your vehicle air system..... if only cars could talk :D

I'm glad they can't, well most can't, as the computers hold enough evidence to hang you in the event of an accident. :eek:
Has anyone done anything to their car's intake/exhaust/ or added a turbo/charger or supercharger? o_O

I've done an aFe CAI, and you can see it on the first page. As far as exhaust there are a few out there, and you can go to the correct section to see all the different ones. No one has a turbo/super charger for our cars, yet. Hope this helped.

Thank you for the information. I figured because of how new this car is that it was kind of optimistic to hope for a turbo/supercharger xD
OK, as promised I've uploaded a sound clip to YouTube that lets you hear what the Takeda CAI sounds like on a 2015 Lexus RC 350 with F-Sport option. The exhaust is stock. I've tried to include as many different driving conditions as possible. If you have any questions let me know.

At no time was the speed limit exceeded on surface streets or the freeway. The CAI makes the car sound like it is going faster than it really is.

Did you get any fuel economy MPG gian and HP gain?

Has anyone compare the afe intake with the K&N drop in filter?
