Very nice intake.

 

HP Gains on the Intake =P
xD ~ RR

 

Maybe 5-10 hp gain I think.

 

Holy damn.. That looks legit... Rafi great work.. I think I have to put myself down for one!!

 

Whats the inside diameter of the pipe? 87mm?

 

Ours is 88.9 mm or 3.5" (ID) .. It's been a working proven design since the 2008 IS F launch and we've carried over the same proven design to the 2015+ RC F and now 2016 GS F

Makes about 4-5 rwhp and it's been independently verified by many owners over the last 7-8 years.

Made out of 6061 T4 Annealed Aluminum + Extrude Honed + Anodized

Sleeper • Black


Lexus F • Blue


IS F • Gunmetal for my personal IS F


I've measured the cost of Titanium & manufacturing to my standards, many times through the years.. Especially after our reseller in Japan took our design and relaunched it in Ti version.
The cost quadruples for the product, yet the power remains the same.. So that is why even after many requests through pm or even on here we have never changed the desgin.

Glad to see RR Racing take this to the next level to give more F owners materal options.
Plus conceptually, theirs is slightly different deleting the Valve cover PCV vacuum lines.

Joe Z, Have been waiting patiently for your intakes to become available again for a few months now. when are these avail again?

 

Anodizing run starts this coming week... Sorry for the delays..

This month for sure

Joe Z

 

Thank you.

We decided not to do a group buy because that would delay shipments while waiting for the GB to complete, and many of you PM'd me that you want this for Xmas....

That said, please PM me, and I will email you a very nice discount code for the introductory offer.

Intakes will ship either Wednesday Dec 16th, or Thursday Dec 17th, we are just waiting on silicone couplers.

Link to purchase is here:

thank you!

Does ISF and RCF have the same engine?

 

No they don't

 

Actually it is the same engine. The differences are relatively minor. The main reason RCF makes more power is the higher compression ratio.

Rafi

 

Yeah I should have specified the differences are internals, header, intake design, etc (iirc)

 

Would like more info on different intakes as well!
Making a parts list as I prepare to purchase an ISF of my very own.

 

That's what I though from reading some article. It's a tune IS F engine for 51 hp more power.
