what are cryogenically treated apex seals are they more of a performance thing or a durability thing.

Cryo-treating is a process that yields results like heat treating. These processes are used to increase the strength & durability of the part. As the the cryo apex seals won't directly increase performance they will allow for more abuse.

cos im looking at geting an adkins rebuild kit soon and I noticed that the adkins cryogenicly treated apex seals cost less then the stock mazda apex seals so I didnt know if that was cos they wernt as good as the mazda ones or somthing. so what your saying is if I were to get the adkins cryo treated seals they would deal with more abuse.

Well this may be confusing, but I'm going to try to explain this. The Mazda OEM apex seals are strong & handle abuse. The Atkins seal I have heard are not as durable as the OEM thus the price difference. The cryo process makes their seals better then the non cryo seals they offer.

Now for the part that may be confusing. Some seals will be harder & take more to break them then others, but when the do break they do more damage to the housings then the softer seals. So it may come as a trade off.

From comments of others that I know the Mazda 2 pc OEM seals are very nice for low to high power cars. Your build will determine which seals to run. There are a lot of different seals offered, ceramic seals tend to be a good choice if you have the money.

Here are a few, but there are far more to chose from

well im aiming for 250hp and I want the engine to be realy durabul but I wount have enough to get ceramic seals or I deffinitly would get them what seals do you recomend that are better than oem seals and are around the same price range.

The Atkins should be fine or the OEM for 250hp, but I have heard good things about the Goopy & RA seals.

I think ill just go with the oem seals even though they are like a 150 bucks more
