Little disappointed that that I didn't get new spring and piston like the products shown in picture I got a small spring all the rubber orings and grease but still gonna use it this product really should have the rebuild kit with everything included to remove from the bpv

Product arrived very quick and will work out just fine, in the picture they had a yellow spring pictured with it so I thought I was getting the yellow spring along with piston and o-rings, in all honesty I really wanted the yellow spring first and a piston rebuild second reached out to Sean Lyle
And he said he would get back with me

I wanted to service my BPV during the Black Friday sale - for Mazdaspeeds miata.
At the beginning the model wasn't available - but a quick mail to the site solved that issue within a day! Making sure I can enjoy the sale.

Took a bit of time (Black Friday) but I got everything I expected in the kit + a NEW set of all 3 springs that came with the BPV which I lost throughout time. I was very surprised to get everything to this extent. Great job guys!

Only thing I could ask is a service guide / link to one on the site.
Happens that I found one online so not an issue - just nice to have.

Ordered this along with a new solenoid. Customer service was more than helpful and sent me a video on how to replace the seals and grease up. These are stand up guys who stand by their product and im happy yo have their parts on my vehicle. Thank you.

Kit came with everything I needed to service my BPV. Grease, O rings and a new piston. Instructions were a little unclear to determine if a seal was made but since I was using the blue spring, the piston did move to almost closed when I plugged the vacuum outlet with my finger. Emailed support, they got back to me within minutes! Car feels much better now and boost is more accurate. I recommend they include instructions with every shipment or provide a link in the box. Had to do some searching to make sure I was doing it right. . the review feature isn't working with my browser so when i put my cursor over the stars it goes to zero so its either 5 or 0. 4 stars....

I only needed one O ring, and the special grease.
I got the o rings, new piston that is different than the current one (for supersize diverter)...

Works really well. My specific application was for a 2015 MK7 GTI. The kit comes with everything pictured EXCEPT the spring. Which sucks because I had to order the tuning kit just to get the spring. Although the spring is not considered a rebuild product, I bought my BPV used and the previous owner lost the yellow spring that is factory which I needed. Then shipping is $15 so it's really like this kit is $32. Which wouldn't be so bad except it was shipped the slowest way possible and took 10 days from order to get here. 10 days! I rate the product 5 stars but the shipping I rate 2 stars. The price is extremely fair but the shipping shouldn't cost more or even equal to the product. Overall I'd buy again. I'll just gripe until it gets here, which will probably be another 10 days.

Thank you for the 5 star review on the product.
Clearly we failed on the shipping of the spring , we will look to improve our service to you .
I accidentally ruined a seal by overtightening. When trying to "fix" my bov I cleaned up the broken seal pieces and unknowingly took off the grease from the bov. This caused my BOV to seep air when full throttle and going into the next gear. I luckily came across this kit and purchased it. I recently replaced all the seals and greased the BOV and have remedied my issue. Shipping was quick and the customer service was excellent.
everything fit perfect and the bov/springs seems much more solid
quick shipping
