I’m very disappointed with this company and its customer service. After spending almost $500, I had to pay for shipping to return items. The gentleman I spoke with on the phone was very rude, which made the experience even more frustrating. Based on my experience, I would not recommend this company.

Can not really trust what they say and advertise First order for about $8,400 (Jan 2025) went somewhat smoothly, still waiting for a refund on “back ordered” parts (it’s now 2026) Second order (Jan 2025) went well, I believe it was for a couple of hundred dollars Third order for almost $10,000 (Mar 2025) was never shipped and they refused to refund my money (hiding behind the description) and the production is no longer on their site… I had to go through my credit card and PayPal (15 months after order and full payment) to get my funds back. If there was a zero start rating I would have opted for it… I completely don’t understand their attitude and how they can be highly rated for some and so badly with others

Was a very long time customer but as time went on the owner Coz first sold me a counterfeit 300 degrees fuel rail fast forward I got a fake Nissan parts and some other questionable parts . . I stopped purchasing anything from these guys soon after

Used to be OK for Z32 parts to Australia but not any more, fedex manage to screw you around for weeks with constant lies regarding delivery, no longer fit for purpose, just go to Amayama and others, can be done cheaper quicker and better else where and not use fedex.

I bought an injector adapter kit a year ago and they were out of stock, so I was up-sold a different adapter kit per their recommendation. The upsold adapter kit did not fit properly and led to catastrophic engine damage. Thinking I caused it with an improper install, I ordered another set of injectors and brought the set to a professional, where they were also unable to get a proper fitment. When I left a review of this product on their website, it was deleted. I finally re-ordered the original czp adapter kit I wanted, and everything fit perfectly. Had I not listened to their first recommendation, I would not have wasted a year, a motor, and my money. THey have not responded to this yet. Even with proper fitting injectors and adapters, their injectors make the car run way too rich. They have not given me any good reason why. I ordered a Nistune license key. It was never delivered to my email, so I contacted CZP. After a few more days of back and forth, I finally got my key. Ordered recirc valves, and was surprised by an email after I paid saying they weren't actually in stock and in fact, back ordered for potentially up to a month. Still waiting for those to ship almost a month later, while they currently list the product on their website as in stock with "fastlane" shipping available. Their wiki is riddled with incorrect / unchecked information. I brought up a specific example and they never responded.

Scam, never received my order.. Ordered some lug nuts on 06/01/2024 but still waiting for them. No tracking etc. available, mailed the company for a refund, did not receive any money & still no solution..

liars, I paid for next day standard, first they didn't ship my products the day of purchase because they said they didn't have the part in stock, because of this and the fact that next day shipping is only valid M-F my parts aren't going to be here Until Monday and I purchased everything on Thursday, that's 5 days until I get my stuff. They should have contacted me directly as my phone number is in my account profile. They are an unscrupulous company, get your parts from Z1 unless you live in PHX.

This place is hit or miss but on the miss side it’s a big miss as the owner is selling customers counterfeit OEM Nissan parts and copied aftermarket parts as originals . If you plan on using CZP stay away from anything OEM and do your research on the aftermarket parts before buying
