The radiator cap is a standard size. This cap should fit your car if your old one does not.

I believe Koyorad states that it only fits their radiators, but you could double-check.

It certainly ought to. In a 2005 G35, it was said to work.

Selected User Reviews For Koyorad SK-C13 Red High Performance Radiator Cap

Koyorad does not include a radiator cap
5/5

This radiator cap is required for all Koyorad Aluminum radiators. I recently replaced the engine in my 1996 Integra with a full-size engine. Honda K-Size Koyorad Honda K-Size Koyorad Honda K-Size Koyorad When I swapped out the radiators in the series, I discovered that the cap was missing. Koyorad requires its own unique cap, which is available for purchase separately. Regardless of what happens, you must wear a koyorad cap. What I didn't like was the radiator's price and the fact that it didn't come with a cap. It would seem that it would come with the radiator that was purchased, but it does not. So, $30 more. 00, and it's been three days since I've received the cap. I only had one problem. The cap fits snugly and there are no signs of overheating. If you purchase a Koyorad radiator for your project hotrod, make sure to purchase the cap as well. RADIATOR CAP IS SOLD SEPARATELY.

The cap is costly, but it does the job
5/5

My 2002 WRX with the EJ207 engine swap was overheating at idle, and I was having problems with it. It was fine at full throttle, and even when stopped, holding RPMs brought the temperature down. It had to be a coolant leak, I knew it. I looked around a bit. I didn't notice anything until I looked at the coolant expansion tank on the turbo. Around the cap, there was a coolant residue. I'm starting to think the cap is leaking. My overheating issues disappeared after I installed the Koyorad cap.

Cap of excellent quality
5/5

Cap of excellent quality. Japan was the source of this item. My FD RX7's radiator cap was leaking, so I used it to replace it.

5/5

On my Nissan 240sx from 1992, it works and fits perfectly. I'm using a Koyorad KA24DE aluminum radiator, and the radiator cap hasn't failed me yet.

Koyorad radiator is a perfect fit
4/5

I replaced the radiator cap on a car with a Koyorad radiator but a generic cap installed by the previous owner. The coolant was leaking because the cap was designed for lower pressure. Coolant leaks were solved by replacing the cap, which fit perfectly.
