Cel Delete Kit

The installation of catless downpipes will result in an inevitable check engine light (CEL) as the DME will detect that emissions are not being burnt up by the OEM catalyst. To remove this CEL without having to tune it out we offer the CEL Delete Kit which is comprised of O2 sensor spacers specifically calibrated to comply with BMW's parameters for a functioning catalyst. These install into the post-catalyst O2 sensor bungs, effectively removing the CEL that would otherwise appear.

Vehicles manufactured from 2019 onward are highly sensitive, and the Check Engine Light (CEL) may not always be eliminated. However, the modification may help delay its activation.

Great quality, not cheap but totally worth this price!
Size: King
I bought this pillow for my husband because the other I’ve purchased have gone flat. So far he is loving this pillow. It has great loft and comes with extra to adjust if necessary. I’m going to purchase one for myself as well! It is extremely comfortable!

You have to reposition to stay cool
Size: Queen
It's okay...it isn't much better than other cooling pillows I have had. If I had known you can't wash this pillow, only the outside cover, I would not have paid so much. The cover is cool to touch but the heat from your head will penetrate the pillow and I am constantly having to turn it over. So it is ok but way overpriced.

I like my Sujo FlexCool pillow
Size: Queen
It cools nicely and it is possible to add or remove fill to optimize preferred comfort. Quality made and very comfortable for me after I added some of the fill provided with the pillow.

This was not for me
Size: King
Hmm… I didn’t hate this pillow but I was not blown away either. I’ve been using Sleep Number pillow, and since the price range was similar, I thought this might be a great alternative, especially when it’s hot. Even though I was able to adjust the filling, I couldn’t find the right shape/density. And I found that this pillow felt hotter when I was sleeping. After trying it for a few weeks, I went back to my Sleep Number pillow. The quality was fine. But I guess everyone is different, just like some people prefer a softer mattress and others don't.

Best pillow ever.
Size: King
How much did I like this pillow? My wife and I both loved it so much that we purchased another one. I think that says it all! The pillow arrives in a large box (king size pillow). It does NOT arrive all flattened and squished in a vacuum bag like some others do. I did place it on my back porch to air out for a while, just because that's what I do with any new bedding. I did not have any issue with scent or odors from either of my pillows. Its clearly well constructed with high quality materials. It comes with a smaller bag of extra stuffing if you want a slightly firmer pillow. We have not used any of the extra stuffing... we think the pillows are perfect as is! When I ordered the first pillow, I thought the price was a bit on the high side. After using it, I had no hesitation purchasing a second. This pillow is well worth the price. If anything, I feel this pillow is a great value at its price. Its not too hard, not too soft. Its the goldilocks pillow! I give this pillow my highest possible recommendation. Its simply a great pillow.
