A must-have item for the AP1 drive-by-cable engine. CSOhara IAT Sensor Insulation Gasket Kit is an insulating gasket that blocks secondary rise in the intake air temperature sensor body due to surge tank heat. Since the intake air temperature value decreased after installation, it can be confirmed that the ECU was recognizing a value higher than the original intake air temperature due to the influence of heat damage.

The fully open temperature is more important for thermostats than the opening temperature. This is a 68℃ low-temp thermostat with a valve opening setting 10℃ lower than the stock thermostat. The fully open valve temperature is set at 83℃ to increase cooling efficiency during sports driving.

As a water temperature countermeasure for sports driving and as a refresh menu. CSOhara Wide Core Stock Radiator is a calorie-up radiator that combines a stock-compatible tank with a 26mm wide core. It also supports sports driving when used in combination with a low temp thermostat.

In-tank type anti-bias baffle. CSOhara Fuel Tank Anti-bias Baffle is a baffle plate that prevents stalling, breathing problems, etc. caused by fuel imbalance due to lateral G during turning. To install, you do not have to use any bolts or stays, just hook the stay part that comes out of the product onto the rib of the tray inside the tank and fix it.

Intake efficiency is increased by expanding the bore diameter and butterfly diameter. The new butterfly allows for tuning that also serves as a refresh. In order to improve quality, the body part has been blasted.

It's time for AP1.5 & AP2 to refresh its throttle body, too. Intake efficiency is increased by expanding the bore diameter and butterfly diameter. The butterfly has been newly adjusted (from Φ64 to Φ66), allowing for tuning that also serves as a refresh.

CSOhara Aircon Less Short Timing Belt is designed to be workable during replacement and that cancels the air conditioner compressor pulley. Even in cars with air conditioning, it can be used only during sports driving to protect the compressor and reduce horsepower loss.

CSOhara Aircon Less Reinforced Short Timing Belt utilises the next-generation material EPDM.

• Improved durability under high temperatures

• Improved durability under harsh usage conditions

• Reduction of a moment of inertia due to weight reduction

• Reduced squealing due to improved anti-squeal performance

CSOhara Stock Oil Cooler Deleting Kit is designed to eliminate waterway heat damage when using a third-party oil cooler. By removing the stock water-cooled oil cooler, waterway pressure loss is reduced and water and oil temperatures are prevented from rising together.

CSOhara Air Pump Canceling Unit is to delete the stock air pump and the ancillary parts for sports driving. This unit includes an ECU canceling function to maintain the stock air pump unit deletion in the engine room. The kit contains a control box, wiring harness, suction plug, solenoid shield plate and gasket, and rubber cap.

CSOhara Speed Limiter Canceling Unit can be used in combination with any third-party ECU units which cannot cancel speed limiters, such as E-Manage, O-bit, and F-CONis. Also for users who want to cancel the speed limiter anyway.

For those who want to sports-driving even with a stock ECU. CSOhara One Touch Harness is a coupler-on kit that only has a speed limit cancel unit and electric fan forced control switch on the jump harness. *It is also possible to connect an air pump cancellation unit at the same time.

CSOhara E-manage Ultimate and Data Set includes TRUST Greddy E-Manage Ultimate, CSOhara original harness kit, and CSOhara original data for AP1 (Drive by cable only). In addition to fuel increase/decrease maps and ignition timing correction maps, VTEC control using external output functions, fuel and ignition correction based on water temperature/intake temperature, electric fan control, and even limiter cancellation is possible.

No aperture, Φ70 muffler with a noise reduction design that emphasizes output. CSOhara Silent Sports Exhaust System uses SUS material with low heat shrinkage and excellent sound absorption. A silencer that incorporates sound reduction know-how into its internal structure.

In response to customers’ demands, we have prepared a silencer-less mid piece (middle pipe) for CSOhara Exhaust System users.

A new mold measurement design was taken from the stock AP2 catalyst. It is also compatible with AP1 by changing the O2 sensor boss position to AP2. Measures for the O2 sensor harness tension issue when using in AP2. Special gasket, bolts and nuts included.

Φ70 pipe without aperture restriction from the front flange. Use it for vehicles where sports catalyzers and third-party catalyst adapters are insufficient. By offsetting the O2 sensor boss, we have taken care to ensure that both AP1/AP2 can install it without straining the harness. Special gasket, bolts and nuts included

Bulk buying is recommended. Triangular flange side muffler gasket for replacements. It is a friendly design with a ring press fitted into the inner diameter to improve durability. If using a different diameter, please specify the larger diameter size, provided that the inner ring part is in close contact.

Reduces swirl resistance due to level difference with the exhaust manifold. The SARD catalyst has an inlet diameter of Φ76.3, which prioritizes purification efficiency, compared to a typical Exhaust manifold outlet of Φ60.5, and is an adapter for the purpose of rectifying the turbulent flow of exhaust gas due to the difference in pipe diameter.

This black chrome plated Honda badges are recommended for luxury users who find matte black too dark and genuine silver plating too bright. A set includes one for the front bumper and one for the rear trunk.
