Replaced factory head bolts with Inline Pro studs myself in 2018 Accord 1.5T with L15BE engine as insurance against common head gasket failure. Used 1B1 method without removing head. Car is running with no issues.

Inline PRO L15 M-series M10 Xtreme Head Stud Kit | 16-22+ Honda Civic 1.5T, 23+ Integra 1.5T, 18-22+ Accord 1.5T, 17+ CRV 1.5T

I was scrambling to fix my family ‘17 CRV 1.5T and the mechanic gave me a tight time window to work with. I was able to get my parts on time with helpful suggestions from team Unity. Upgraded head studs should help keep my Honda on the road.

I just installed these in 19x9.5 +40 on my 2025 Civic Type R. They fit absolutely perfectly in this size with 3mm spacers (to clear Brembos). I love the look and Humza was excellent to work with.

Great piece

The Catch can is well designed & has an excellent construction. Everything lines up & it won't break during installation. Once installed, it very accelerated via the dipstick or threaded lower half. They are debated for my DE5, but will see next oil change. Shipping was fast! Only one sticker, come on Radium!

Great brake feel gets rid of a lot of the squishy pedal. Install was easy even with the old callipers. But I bought these to see if they would help with the problem of warping rear rotors. They did have had a few hard stops from higher speeds and rotor are still straight.

Excellent addition, easy to install with plenty of options. Great service from Unity made this an easy install.

Perfect shipment fast and easy love the service
