Default Re: Ebay CSL diffusers

I installed my happybuyitnow diffuser just now. Given how much people rave about the fitment, I was a bit disappointed. Aside from the corners, the diffuser sticks out, and it is pretty bad on the left side. I may be able to trim some of the back side to improve fitment. Left and right side spacing is good. Left corner sits flush with bumper and spacing is good. Right corner goes in too much and the gap is a bit more than it should be.

Weave isn’t perfect, but I did not expect it to be, given that it’s a $320 eBay diffuser. Paint match is good. There is a clear difference in the shade, but it blends well with bumper paint when sunlight hits it. I wish they had done a better job painting the top edge because you can see all of the imperfections. The metal tabs are dumb.

Happybuyitnow’s communication was great. The diffuser arrived within 24 hours of it being shipped out, which was very impressive. I expected it to take 7-14 days. Diffuser was protected well in the thick, cardboard box.

Fitment 7/10
Paint 8/10
Overall quality 7-8/10
Service, shipping, communication, etc. 10/10

That's not bad for $320 considering the paint is pretty good. An hour or two trimming it and getting it to fit a little bit better is what you get for that price

Did they raise the price? These were $275 painted/shipped. Kong, look at my post about drawing it inwards with zip ties

I got mine $275 painted/shipped also in May. Paint match to Imola was pretty darn good but mine sticks out just like yours but on the right side. It also seems to “pop” out from time to time.

just got mine from Happybuyitnow for $299 shipped.. took a week to come in and it fits really well actually.. quite surprised for the price.

The paint isnt great.. the outline they do around the CF could be better..

Given all the talk about how great the fitment is, I am not happy with his response. Lesson learned – don’t buy eBay.

Kong, fitment is on you. You can do a better job. Mine is near perfect after my tricks. No aftermarket body part is going to have OE fitment right outta the box, you know this.

Zip ties won’t work. It needs to be shaved. I followed your zip tie method to make left corner sit flush.
