a very nice kit
The kit was a savior, it had seals in it that I didn't even know I needed. Some of the items are slightly wanting when compared to OEM, but they did the job well at a good price.

2014 Cruze 1.4
All the gaskets fit perfectly, the ones I replaced were brittle and worn out. It's been about a month and no more leaks from the oil cooler. I would recommend to anyone with a leaky oil cooler. I would also recommend replacing the oil pipe feeder from the turbo to the block while you have everything apart.

2018 encore
The seals for the actual oil cooler are thinner than the originals so don't work.

Works for a 2013 sonic 1.4l turbo LT
Got it from Amazon warehouse for like $20. Was like new. Used all the gaskets when I bought a cheap oil cooler and wanted good gaskets inside. Plus you need this to replace all the gaskets when you're in there doing the cooler. So you don't find out one started leaking when you put everything back together.

Didn't fit my oil cooler.
This product does not fit the Chevrolet 1.4 turbo with an oil filter housing marked UFI. This appears to be for the housing marked HENGST. this was not made clear by the seller. Quality of everything felt good. Order with caution.

no tengo fotos pero quedo prefecto en un cruze 1.4 turbo 2014, le cambie los sellos del enfriador con este kit, me pareció excelente la calidad, hice el trabajo hace 2 meses y aun no tengo quejas pero se que cumple la calidad, es un kit muy completo, solo le faltaría la junta para el múltiples de escape pero de ahí en más todo bien, es un trabajo sencillo por hacer pero muy laborioso.

Good sealing parts but a bit over-priced.
