Description

2004.5-2005 Chevrolet / GMC HSP Cold Side Tube to Factory Bridge HSP DieselThe LLY Duramax has a very restricted charge air system from the factory. After realizing the potential power loss from the small diameter factory tubes, we increased the size of the tubing to 3'' which proved major power gains over the factory intercooler system. While dyno testing the HSP upgraded intercooler tubing, we saw incredible horsepower and torque gains from such an over looked component. This Tube will flow 53% above what the factory unit

Excellent Dahlia Seeds — Huge Difference in Quality
Size: 1-Pack, Style: Zinnia Dahlia, Size: 1-Pack, Style: Zinnia Dahlia
Excellent germination rate and very fast growth! I planted these seeds side-by-side with another Dahlia seed packet from a different seller on the exact same day under identical conditions, and the difference has been amazing. By day 23, these seedlings were already thriving — healthy, vibrant, and growing quickly with a very high germination rate. The plants look strong and vigorous, and I’m extremely impressed with the quality of the seeds. If you’re looking for Dahlia seeds that actually perform well and establish quickly, I would absolutely recommend these. I’m excited to see them continue growing and blooming

This package had more than the pkg that was supposed to have 4000, but they are coming up slowly. It is dry here, I have been watering , just enough to get the ground wet and they are scattered, but some are coming up. I also watered the space supposedly where i spread seeds from the supposedly 4000 seeds pkg. They are not coming up as much!

Didn’t get a review on the garlic powder
Size: 1-Pack, Style: Zinnia Dahlia
The seeds were okay but the garlic powder that I ordered was smaller than usual is a case of bait and switch
