We can now offer this sought after single exit catback system for your Series 1 RX-8 from HKS.

Inspired and designed from endurance and GT racing in Japan, HKS developed its Hi-Power Exhaust system for turbocharged applications. HKS has incorporated this new race inspired offset muffler and piping design into many street applications, which offers a greater flow and higher-PRM power gains due to the less restrictive design. This is achieved by eliminating unnecessary bends for the straightest exhaust path.

• HKS Hi Power Catback Exhaust
• Piping Diameter – 75 mm
• Tip Diameter – 97 mm
•  Single Sided Exhaust for N/A and  Turbo Applications with Adjustable Length Ti Tip
• Lighter then full twin tip backboxes.

The Super Power Flow reloaded kit from HKS has been designed to reduce intake air resistance by removing stock intake pipes that can cause turbulence due to the corrugations normally found in them.

The pipes are made from aluminium and include 2 x 150mmx60mm diamiter HKS Super Power Flow Air filters in green.

Each filter has an easily replaceable “Dry 3 layer” foam filter mounted in to the signature HKS filter frame.

Dry 3 layer type Super Filter was newly developed. Intake efficiency, dust collection performance and replacement cycle are highly balanced. It is long life type filter.

Each kit includes everything required to carry out the full conversions from the stock intake airbox system to the HKS Racing Suction Reloaded setup for your RX-7 FD.

The improvement brought from this conversion should have a noticeable effect to the engine response, and power output.

The Kit includes

• 2 x Super Power Flow Reloaded Filters
• 2 x Intake Hard Pipes
• Silicon Coupelers
• Hose clamps
• Fasteners, Gaskets and brackets.

Please note that delivery may take up to 28 days if not in stock.

Take things a leap further with the Racing Suction Reloaded Intake kit.
The Racing Suction reloaded kit from HKS takes things a leap further by improving on the Super Power Flo Reloaded intake system to reduce intake air resistance even further by removing most of the stock intake pipes that can cause turbulence due to the corrugations normally found in them.

The pipes are made from aluminium and include 2 x 150mm-70mm diamiter HKS Racing Suction Reloaded Air filters in Yellow.
Each filter has an easily replaceable “wet 2 layer” foam filter mounted in to the signature HKS filter frame.

Wet 2 Layer Type Super Filter has been used and proofed long time. It reduces intake resistance and special high viscosity glue has high dust collection performance. (These can re replaced with the 3 layer dry type filter element)

Each kit includes everything required to carry out the full converisons from the stock intake airbox system to the HKS Racing Suction Reloaded setup for your RX-7 FD.

The improvement brought from this conversion should have a noticeable effect to the engine response, and power output.

Single Turbo. Airflow less setup requires F-Con Vpro or similar.
Compatible with air pump.
For use with R Type Intercooler (13001-AZ001,2)

Get the power-up plus for the price of normal change for a exciting driving experience!!

TO4z can produce from lower range of rpm to higher range of rpm to increase the peak power(about 400ps).
As the big single is in advantage of power, FD3S has more boost presure, more air, and more power. And still it has compactness kit for tuning-up. This kit is suitable for one who wants to change the deteriorated stock turbine.

This Full Turbine kit is low cost single turbine and for novice at single turbine or a RX-7 (FD3S) owner who wants to change the original turbine.
Adopted 4 holes flange to attaching part of the turbine and front pipe which makes it easy to install.
Includes chamber pipe which matches original intercooler layout. With the chamber pipe it supports the original intercooler and R type intercooler V system.

HKS Silent Hi-Power mufflers offer high performance and sporty appearance with the added benefit of reduced noise levels making it the best choice for more mature enthusiasts. Silent Hi-Power mufflers are constructed entirely of SUS304 grade stainless steel for high lustre, long lasting performance. For certain applications, HKS has introduced the “Silent Chamber” which removes a lot of the lower frequency noise that can often be heard into the cabin even when cruising. The silent chamber removes this uncomfortable noise but due to its closed end design, only a minimal amount of exhaust gas flows into it, meaning that the disruption to exhaust gas flow through the entire system is minimized and there is no harm to performance.

To prevent any unwanted delays when processing your order please select the correct application for the year of your RX-7 FD from the drop down menu found next to the “add to cart” button.

Application options;

• 91/12-98/11 (Ver 1-4)
  
• 98/12-02/08 (Ver 5-6)

The filter with integral Neodymium Magnet technology inside

A new concept oil filter which improves oil pressure drop and flow properties by approximately 30% compared to current sports oil filters. Large diameter of “Super Intake Hole” and newly developed low resistance hybrid filter allow low pressure loss. Engine response is alos improved by reducing the stress on the engine.

Most sports oil filters are prerequisite for using the high viscosity oil and therefore filter paper strength is prioritized whilst sacrificing absolute pressure loss properties. HKS Hybrid Sports Oil Filter has readdressed filter strength and overall structure to provide the oil flow that the engine requires and pursue HKS’ ideals in what is required from a sports oil filter.
