Collection: Engine Performance

Although my part was just an o2 spacer it was well made, arrived quickly, and I liked it’s packaging

Got this harness/sub harness and shipping was quick. Looks great quality and labeled for easy install! Customer service was a great help with all the questions I had.
Note:-- this harness has already bypassed the vtec pressure switch so it has no plug for it! I had to do some research to find out but don't worry if you see no plug

Very high quality harness, very well labeled! Had a few difficulties installing, but after contacting customer he quickly walked me through every step and had it fixed in no time. Also the "customer service" was the owner contacting me himself! That should speak for itself! Will definitely be a long time customer.

Exactly what I needed

Great customer service

As soon as I turned it over, I saw a huge difference in the way it was running! Buying again when needed.

Was what I needed for my custom radiator setup

Fast shipping

Love it thanks

High quality, sounds great

Exactly as specified. Well packaged, so delivered in perfect condition. Quick delivery dates and confirmation. Honda builds great cars, but sometimes a decade or 2 makes the connectors more brittle. This is a great place to get quality replacements.

Had one very small issue, and it was taking care of extremely fast and extremely professional. I was pleasantly surprised and will most likely be a returning customer.

Pcv breather box plug fits perfectly.

Looks very nice feels durable and well made happy i found a budget friendly engine harness
