ALS vs E&J Autoworks apex seals
 

Hi guys,

I searched, without success. ALS seems to be hard to find but I found E&J Autoworks apex seals. Seller told me they are an improved version of the ALS. He claims "better compression, longer life and more power." What do you guys think?

ALS seals were just rebadge E&J seals. Edgar the CEO of E&J has cut ties with ALS and is making a name for himself with an improved version of the old ALS seals which by the way was Edgar's creation, a lot of R&D has gone into the new seals; thus producing some of the best seals that are in the fastest rotaries in the world.

ALS < E&J (improved version) = P U R O P O W E R P A P A :icon_tup:

I recommend RX Parts. Just because a seal is in the fastest rotary doesn't mean it performs best in a street application. Things like wear and longevity come to mind. I run them in everything from stock to heavily modified cars. They are super strong, yet do not trash the rotor housings like some other seals. In fact I've had them in a car with an entire season of racing where the customer didn't premix. I don't recommend it, but after disassembling the motor for a refresh the housings were mint. I sell them for $499 for the standard set, or $529 for the coated set with an anti-friction dry lube coating. I have never had a failure with them in the 6 years + I've been using them.
