Subaru Impreza

Review
After having this HKS Twin Power DLI installed in my ride, I noticed a massive difference in my ride. I now drive really smoothly, I do not feel any jerkiness when I move off. Also, while idling, I noticed it to be much smoother, which means my engine has been fed with the right amount of power. I now do have a more gradual acceleration, and this was a really good factor since I just love the pickup power of my ride. This boosted the overall experience I am having with my ride!

What I like
My engine performs way smoother now.

What I do not like
Expensive pricing.

Review
My engine used to misfire on occasion, but now that I've got this installed, misfires are a thing of the past and my engine runs so smooth it purrs! Idling is also a lot smoother. Revving up the engine from both cold starts and warmed-up starts is noticeably quicker (used to be 5 secs for my car, now down to 2-3). The exhaust smell is slightly better now, which means that it's done its advertised job of burning off more fuel for more efficient ignition.

What I like
1. Engine running is a lot smoother.
2. No more misfires.
3. Smoother idling
4. Revving up is a lot quicker

What I do not like
The Price.
