Lowkey.. this install was NOT fun LOL curse you Subaru for this difficult installation. I am glad IIR came in clutch to provide this product for me. ☺️
Absolute must have for any EJ! Great quality parts as always.
The original mod, complete with full instructions. Quality materials
I chose to buy and support this particular brand being as he created it regardless of how simple the kit may seem. Great quality parts. Install was straight forward and simple. I pinched the mod off with hose pinch off clamps while I bleed/burped the coolant system, then removed the clamps and continued the process. Also used the recommended permatex grey and let it cure 24 hours prior to adding coolant. Ran into 0 issues with heat or any leaks.
Cant beat a little piece of mind knowing this will help with cooling things down a little
Works as intended!
IIR is great and will be doing a lot more business. All products delivered on time and in great shape ready for install. A+
Easy install and Keeps cylinder 4 cool!
Easy to install and a must have on any subaru!! Great quality for sure!!!
